 9      TRANSCEIVER MODES

        The DR-600T/E has 4 modes;  VFO mode, MEMORY mode, CALL mode and
        ARM mode. The DR-600E does not utilize CALL mode.

 9.1    VFO MODE (Variable Frequency Oscillator)

        Press the VFO key.  The transceiver will be in VFO mode. This mode
        is used to change frequency and select desired channel step, offset
        frequency (up to 10.995 MHz by 5 kHz), tone frequency (38
        frequencies in Hz), etc.

 9.2    MEMORY MODE

        The following guidelines will help you to program and manipulate
        memory channels. To select the memory mode, press the "MR" key.
        The most recently used memory channel will display :

                o Frequency
                o Memory channel number
                o Other programmed functions

        You can scan the memory channels with the "Scan" key, elect to skip
        any memory channel with the (Skip) key, or select the scan type
        with the (S.TYP) key  (the programming these functions is detailed
        further in this manual).

        The DR-600T/E has two (02) banks of memory channels:

        1ST the main bank of 28 memory channels that are accessed with the
        MR(MW) key.

        2ND the ARM memory channels. ARM gives you 10 additional memory
        channels.






 9.3    SCROLL MEMORY

        Scrolling the main bank of memory channels up or down can be done
        one of two ways, the front panel or microphone.

        Example from the Front Panel

          1. Press the MR key.

          2. Use MHZ up or MHZ down key on front panel.

        Example from the Microphone

          1. Press the VFO key.

          2. Enter C02 on the microphone keypad. Now your in memory mode.

          3. To increase memory channel number, enter C08, to decrease
             enter C09.

 9.4    MEMORY WRITE

        To write functions to any memory channel, perform the following.

        Example 1:

          1. Select VFO mode.

          2. Select the VHF or UHF band.

          3. Select the receive frequency.

          4. Select the repeater shift - or +, and the required offset. If
             required - consult your Repeater Directory.

          5. Select the proper PL [CTCSS] sub-audible tone. If necessary
             consult your Repeater Directory. After selecting and setting
             the required functions you can write (store) those functions
             to a memory channel in a couple of ways.

          6. Press the "FUNC" key. The "FUNC" indicator and memory channel
             number will be displayed on the LCD.

          7. Turn the Main Tuning Dial clockwise to choose the desired
             memory channel number (clockwise to increase, counter
             clockwise to decrease).  Select the desired memory channel
             number (1 to 28). The following, (1L, 1U, 2L, 2U, and A) are
             special use channels explained later in this manual.

          8. When you have selected the memory channel you want, push  the
             (MW) key to write (store) to memory.  The LCD will return to
             VFO, and selected functions will be stored in the last
             displayed memory channel.

        You may store VHF or UHF frequencies and functions in any one of
        the 28 memory channels.  Be advised that there are only 28 main
        memory channels, storing a VHF or UHF frequency in any channel will
        utilize that channel for that setting ONLY. You will have to
        overwrite on that used channel to utilize it for another band.
        For example: the factory setting shows memory channels 1 - 14 on
        the VHF band side, and 15 - 28 on the UHF band side.  You can store
        a VHF frequency and functions in channel 18.  That channel will
        then be displayed on the VHF band side, and no longer on the UHF
        band side.  Scrolling through the UHF band side will display 15,
        16, 17, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28 only. Channel 18
        will not display on the UHF band side.

                                ***NOTE***

        Several of the memory channels have been reserved for "Special
        Functions": (1) Channels 1L, 1U, 2L,& 2U are reserved for Program
        Scanning, and (2) Channel A is reserved for programming the ARM
        memory channels.

        Example 2:

          1. Select the desired VHF or UHF band, as described above.

          2. Press MR for memory recall and use the MHz key to select the
             desired memory channel. You will only be able to select those
             memory channels displayed on the band (VHF or UHF) you
             initially selected.

          3. Press the VFO key.

          4. Select a frequency, shift direction, shift value, and PL tone
             frequency.

          5. Press "Func" key first, and then the (MW) key. The frequency
             and functions chosen will be stored into the previously
             selected memory channel.

10      CALL MODE

        Press the CALL key. The transceiver will be in CALL mode. The CALL
        Mode allows a single key to access an immediately desired
        programmed frequency.

10.1    CALL WRITE

        You can set a desired frequency (and other functions) into your
        CALL Memory Channel by performing the following steps.

          1. Select VFO mode.

          2. Select the frequency you want to store as your CALL frequency,
             repeater input shift, PL tone, etc.

          3. Push the "FUNC" key

          4. Push the (CALLW) key to store frequency in to the CALL Memory
             channel.





11      ARM MODE (AUTOMATIC REPEATER MEMORY)

        There are ten ARM memory channels. These channels are used by ARM
        exclusively and are separate from the main memory channels.
        Frequency storage for ARM can be achieved automatically or by
        manual entry. The main purpose of ARM is to store repeater
        frequencies automatically.

11.1    AUTOMATIC ENTRY (ARM)

        To write repeater frequencies and functions to any ARM
        memory channel, it is necessary to first setup storage for
        ARM via VFO mode.

          1. Select VHF or UHF VFO mode.

          2. Select the receive frequency, shift and if required, PL (CTCSS
             sub-audible tone).

          3. Press the "FUNC" key, and the memory channel number will
             be displayed on the display.

          4. Turn the Main tuning dial clockwise or counter clockwise until
             the "A" memory channel is displayed.

          5. Push the MW key.

          6. Press the microphone PTT switch. If the DR-600T transceiver
             receives an acknowledgement from the repeater, the frequency
             and other functions will be memorized in channel A1.

11.2    AUTOMATIC REPEATER SHIFT (ARM)

        Here's an example of how to have your Alinco 600 automatically
        shift when you enter in a frequency.

          1. Enter into the VHF VFO a known frequency above 147.000 and
             include the positive offset!

          2. Press the FUNC button.

          3. Press the up/down buttons on the mic, or turn main tuning dial
             until memory channel A is selected in the display.

          4. Press the MW key.

          5. Press PTT on the microphone and identify your station as
             testing. After you have heard the squelch tail on the
             repeater, the frequency you just entered will have been
             stored into ARM memory.

          6. Enter a frequency below 147.000 and include the negative
             offset.

          7. Press PTT once! This clears the display but doesn't transmit.
             The shift limits have now been understood by the DR-600.
             Select any frequency further and the shift will automatically
             be inserted with the frequency.


                                ***NOTE***

          The 10 memory channels in ARM cannot be selected individually for
          programming. Each frequency stored will push the last previously
          stored frequency into the next ARM memory and so on and so forth.
          After all ten memories are used, the oldest frequency in ARM will
          be discarded. The ARM is limited to recording within the initial
          Mhz frequency.

11.3    MANUAL ENTRY (ARM)

        If the repeater is not equipped to answer your DR-600T/E, it will
        be necessary to manually write your entry into the first available
        open ARM memory channel.

          1. Select VHF or UHF VFO mode.

          2. Select the receive frequency, shift, and if required PL
             (CTCSS) sub-audible tone.

          3. Press the "FUNC" key, and the memory channel number will be
             displayed on the display.

          4. Turn the Main tuning dial clockwise or counter clockwise until
             the "A" memory channel is displayed.

          5. Push the MW key.

          6. Push "FUNC" key.

          7. Push "ARMW" key.

          8. If you wish to select another frequency, make sure it is in
             the same Mhz range. Selection of a frequency out of the Mhz
             range will not be stored.

                                ***NOTE***

          The 10 memory channels in ARM cannot be selected individually for
          programming. Each frequency stored will push the last previously
          stored frequency into the next ARM memory and so on and so forth.
          After all ten memories are used, the oldest frequency in ARM will
          be discarded. The ARM is limited to recording within the initial
          Mhz frequency.

          Example:

             Initial frequency in "A1" is set to 147.015 Mhz, then the
             upper frequency possible to program for the ARM bank is
             147.995.

11.4    SCROLL ARM MEMORY

        To access the ARM bank of memory channels push the ARM key. The LCD
        will display "A" and the memory channel number, indicating that you
        are in the ARM bank of memory channels. You can engage the same
        features in the ARM memory bank as you can in the main bank of



        memory channels. You can scan, skip, set the type of scanning in
        these memories by engaging those functions, described later in this
        manual.

        You can scroll the ARM by:

          1. Turning the Main Tuning Dial; clockwise to increase, or
             counter clockwise to decrease.

12      PRIORITY FUNCTION

        This function allows a one second scan of the user-selected
        priority frequency and a five second scan of the other
        frequencies in the VFO Priority, Memory Priority, and Call
        Priority modes.

12.1    VFO PRIORITY

        Desired priority frequency stored in any of the main Memory
        Channels will be scanned for one second, and the last selected VFO
        frequency will be scanned for 5 seconds.

          1. Store desired frequency in any memory channel.

          2. Select VFO mode and a VFO frequency.

          3. Press the "PRI" key.  The PRI indicator will appear on the LCD
             and VFO Priority scan will begin.

        The last selected memory channel will be scanned for one second,
        the VFO frequency will be scanned for five seconds. If the
        microphone PTT is pressed while on the VFO frequency, the priority
        channel will NOT engage until the PTT is released.

        If the microphone PTT is pressed while on the priority channel
        (memory channel 1), the Priority function will be canceled, and the
        transceiver will remain on memory channel one. The DR-600T/E will
        return to the VFO frequency.

12.2    MEMORY PRIORITY

        This is the reverse of the VFO Priority mode. The VFO frequency
        will be scanned for one second and the memory channel will be
        scanned for five seconds.

          1. Select VFO and a VFO frequency.
          2. Press MR to select memory mode
          3. Select a memory channel containing the desired memory
             frequency to be scanned.

        Any memory channel in the main transmitting band can be selected
        for Memory Priority Scan. You are not restricted to memory channel
        1, as in VFO Priority Scan.



          4. In the memory mode, press the "PRI" key. PRI indicator will
             appear on the LCD and Memory Priority Scan will begin. The VFO
             frequency will be scanned for one second and the selected
             memory channel will be scanned for five seconds. If the
             microphone PTT is pressed while on the memory channel, the
             Priority function will stop until the PTT is released.

12.3    CALL PRIORITY

        The VFO frequency is scanned for one second and the programmed CALL
        frequency is scanned for five seconds.

          1. Push the "CALL" key to access your programmed CALL frequency.
          2. Push the "PRI" key, the PRI indicator will display on the LCD,
             and the CALL channel will be scanned for five seconds, and the
             current VFO frequency will be scanned for one second.

13      SCAN

        The DR-600T/E offers various scanning options and 4 scanning types.
        These scanning options are:

        Band Scan (VFO mode)          - scans entire band.

        Program Band Scan (VFO mode)  - scans programmed lower to
                                        upper frequencies.

        Memory Scan                   - scans memory channels in
                                        selected band.

        Memory Channel Skip           - permits unwanted memory
                                        channels to be skipped
                                        during memory scan.

        ARM Scan                      - Scanning ARM memory

13.1    BAND SCAN MODE (VFO MODE)

        In this scan option all MAIN BAND VFO channels are scanned by
        pressing the "SCAN" key. Frequency decimal point will flash to
        indicate scanning in progress. In the BAND SCAN mode no scan type
        symbol is displayed on the LCD panel. The scanning direction may be
        reversed by rotating the Main Tuning Dial in the direction opposite
        to the current scan  direction. Pressing the appropriate Up/Down
        microphone switch, in Remote mode, also reverses the scan
        direction. All 4 scan types can be applied to Band Scan.

13.2    PROGRAM BAND SCAN MODE (VFO MODE)

        This scan option allows the scanning of a range of VFO frequencies
        between user selected Lower (L) and Upper (U) band frequencies (the
        transceiver must be in the VFO mode to initiate this scanning
        option).  Frequency Lower and Upper ranges are stored in 1L & 1U
        respectively for the VHF Band, and 2L & 2U respectively for the UHF
        Band.

        Storing the Lower and Upper Ranges

             limits.

         10. Press the "SCAN" key to start scanning between the programmed
             lower and upper limits. Scan direction can be selected by
             turning the main tuning dial in the desired scan direction.

13.3    MEMORY SCAN MODE

        This scan option allows the user to scan frequencies that have been
        programmed in any (or all) of the memory channels. Bands may be
        scanned individually or both bands may be scanned simultaneously.
        And the direction of scan (up or down) can be set by pressing the
        appropriate MHz Up/Down key prior to, or during, the scan
        operation. To store desired frequencies (or other functions) to
        memory channels, see the section of this manual entitled "Memory
        Write".

             In any scan mode, you can manually override a "stop"
             and resume scanning by rotating the Main Tuning Dial.

          6. To stop scanning, push the "SCAN" key once more. The decimal
             point indicator will stop flashing, confirming that the
             DR-600T/E is no longer in the scan mode.

13.7    SCANNING WITH ADD MODE

        The purpose of ADD mode is to allow scanning of the VHF lower scan
        limit through through the Upper scan limit and then switch over to
        the UHF scan limits and then repeat this event. In the following
        example you may use VHF or UHF frequencies only. You may not use
        UHF and VHF together in ADD MODE. Lets give an example to make it
        clear.

        Example:

        I want to scan from 145.000 to 145.250 and 147.000 to 147.250. This
        is possible through the use of ADD mode.

          1. Select the VFO for the VHF band.

          2. Enter 145.000 into the VFO.

          3. Press the "FUNC" key.

          4. Rotate the main tuning dial until 1L is shown.

          5. Press MW switch.

          6. Enter 145.250 into the VFO.

          7. Press the "FUNC" key.

          8. Rotate the main tuning dial until 1U is shown.



          9. Press MW switch.

         10. Enter 147.000 into the VFO.

         11. Press the "FUNC" key.

         12. Rotate the main tuning dial until 2L is shown.

         13. Press MW switch.

         14. Enter 147.250 into the VFO.

         15. Press the "FUNC" key.

         16. Rotate the main tuning dial until 2U is shown.

         17. Press MW switch.

         18. Check right now and make sure that the VFO is somewhere within
             the scan range of our example.

         19. Press the "FUNC" key.

         20. Press ADD key.

         21. Press SCAN key.

        The display will now scan 145.000 to 145.250 followed by 147.000 to
        147.250. Turning the main tuning dial clockwise will cause scan
        frequency to increase. Turning the dial counter clockwise will
        cause the scan frequency to decrease.

14      REPEATER OPERATION

        Amateur radio repeaters utilize separate transmitter and receiver
        sections.  The transmitter frequency may be offset either above or
        below the receive frequency according to repeater coordination
        conventions.

                                ***NOTE***

        Repeater offsets are sometimes referred to as "splits". To Select
        Repeater Offset Frequency and Direction:

14.1    REPEATER SHIFTS/OFFSETS

          1. Select VFO mode.

          2. Press the SHIFT key.The current offset (usually 0.60) and the
             minus sign (-) will appear first on the LCD display panel,
             indicating a minus offset of 0.60 MHz (600 kHz). In this
             position the desired offset frequency may be selected by
             rotating the Main Tuning Dial in either direction. The
             DR-600T/E accepts offsets from 0.00 to 10.0 MHz in 5 kHz or
             12.5 kHz steps.

          3. Press the PTT switch to store the selected offset, the minus
             (-) shift and return to the selected repeater frequency.


          4. Pressing the SHIFT key again will show the VFO frequency and
             the plus (+) offset indicator on the LCD display panel. Press
             the microphone PTT switch to store the frequency and the plus
             (+) offset.

          5. Pressing the SHIFT key again will show the VFO frequency but
             neither the minus (-) nor the plus (+) offset direction
             indicator.  In this mode the transmitter is not offset from
             the receiver frequency indicating the simplex mode. The
             transmitter will transmit on the frequency to which the
             receiver (VFO) is set.

             o  The "-" display indicates that the transmit frequency (when
                the PTT is pushed) will be below the receive frequency by
                the kHz or MHz selected.

             o  The "+" display indicates that the transmit frequency
                (when the PTT is pushed) will be above the receive
                frequency by the kHz or MHz selected.

14.2    PL ENCODE/DECODE

          Tone Encode

          1. Push the "Tone" key and the PL (sub-audible) tone frequency
             (in kHz) will display on the LCD for the selected VHF or UHF
             band.

          2. Change to the desired kHz by turning the Main Tuning Dial
             (clockwise to increase, or counter clockwise to decrease). The
             DR-600T has 38 settings from 67.0 kHz to 250.3 kHz). ENC will
             display on the LCD, indicating that the selected PL Tone will
             be encoded (transmitted) with the main carrier frequency.

                                  ***NOTE***

          The purpose of CTCSS (PL) is to reduce co-channel interference
          during band openings.  CTCSS (PL) equipped repeaters will respond
          only to signals having the CTCSS tone required for that
          repeater."

          3. To return to VFO, push the VFO key or the PTT.

          Tone Decode

          With the optional EJ-7U Tone Unit installed, you can set PL
          decode by:

          1. Push the "Tone" key immediately after setting the tone kHz
             (without returning to VFO). DEC will display on the LCD,
             indicating that received PL tones will be decoded.

                                  ***NOTE***

          The purpose of PL decoding is to selectively receive
          transmissions.  Only those transmissions that have the
          appropriate PL sub-audible [CTCSS] tone will be received by the
          DR-600T/E.


14.3    REVERSE (REV)

        In some areas there may be repeaters operating on repeater
        frequency pairs, the exact reverse of another repeater in the area.
        That is, the input of one repeater is the output frequency of the
        other and vice versa. To avoid the inconvenience of reprogramming
        every time both repeaters are in range, the REV key allows instant
        reversal of the input and output frequencies and the offset
        direction. The REV function is also useful to check the repeater
        input to determine if another station is heard directly so you can
        go simplex. To activate the REV function:

          1. Press the REV key The repeater input frequency and opposite
             SHIFT indicator will appear on the LCD display panel.
          2. Press the REV key again to cancel the REV function.

15      AUTOPATCH OPERATION

        Many repeaters offer a telephone link known as an autopatch. The
        DR-600T/E can be utilized in the same manner as a mobile (or
        cellular) telephone. The DTMF (Dual Tone Multi Frequency) key pad
        on the remote control microphone (Standard on 600T) is used to send
        DTMF tones that can activate autopatches and control other repeater
        user functions. The repeater control operator or repeater users can
        advise you on how these functions are used.

          o Optional Function for the DR-600E (European Version)

15.1    AUTODIALER

        This function is used to transmit a memorized DTMF code. A
        programmed number may extend up to 18 digits. The DR-600T/E has
        four autodialer memory channels accessible to either VHF or UHF
        band. There is one memory channel (ARM channel 5)that is used to
        receive  DTMF codes. This particular channel is NOT programmable
        directly from the DR-600T.

          o  Requires the DTMF Unit (EJ-8U) for T/E versions Without the
             use of the EJ-8U, it will appear as if the unit is performing
             autodial, in fact it isn't.

          o  Requires 16 Tone DTMF Microphone T-Standard E-(EMS-3Z)

15.2    AUTODIALER PROGRAMMING

          1. Select the VFO for the desired band you wish to use.

          2. Enter C13 on the DTMF microphone pad. The display will show a
             channel number and a flashing minus (-) sign. If the channel
             has already been programmed previously, the number for that
             channel will be shown.

          3. Select channel by using the Mhz Up/Down key on the front
             panel. You may select 1 of 4 autodialer memory channels. The
             5th channel is the DTMF monitor channel (See DTMF monitor
             section). You cannot store a DTMF sequence

                Channel 5 of the Autodialer cannot be erased

16      REMOTE CONTROL OPERATIONS

        You may control your DR-600 by a remote hand held radio with DTMF
        capability. In this section we will unfold the various REMOTE
        CONTROL features. The Optional DTMF Unit {EJ-8U} is REQUIRED. The
        DR-600T/E can be controlled by a DTMF capable remote transceiver,
        from any location within transmit/receive range of the DR-600T/E
        and remote unit.



      Functions such as:

             o Cross Band Repeating
             o Accessing and Changing Memory Channels
             o Selecting Output Power
             o Selecting Main Band
             o Many other features can be controlled from a remote unit.

        This exciting feature of the DR-600T/E gives the operator the
        ability to transmit from a low power Hand Held Unit through the
        DR-600T/E (Cross Band Repeat) with 45 Watts (approx) on VHF or 35
        Watts (approx) on UHF.

16.1    CHANGE FREQUENCY REMOTELY

        You can only change frequency directly on the sub-band from the
        main band. You can change the VHF frequency from UHF or change UHF
        frequency from VHF. The flashing DSQ indicator must be programmed
        to the main band. If you want to change the VHF frequency, you can
        only do that by coming in through the UHF band side, subsequently
        the UHF band must have the flashing DSQ indicator on.

          1. Enter DSQ number sequence via your hand held to the 600.

          2. Press the "A" key on the hand held and notice how the main
             band display will go blank. New frequency digits will appear
             as they are entered.  When the sixth digit is entered, the
             original display frequency of the main band will return, and
             the new frequency just entered will appear on the sub-band
             side.

        Change Frequency on VHF via UHF Example:

          Lets say that VHF shows 145.000 and I want to change that to
          145.225.

          1. Select UHF frequency with pre-programmed DSQ code.

          2. I will key the PTT button on the hand held and enter my 3
             digit access code. Don't release the PTT yet.

          3. Press the "A" key on the hand held. The UHF display will go
             blank.

          4. Enter the new VHF frequency "145.225". Notice that it will
             show up on the UHF side. When the 6th digit is entered, the
             original UHF frequency will display, and the VHF side will now
             show the new frequency 145.225.

16.2    CROSS BAND REPEAT REMOTELY

        You can place your DR-600 into cross band repeat mode by using a

17      DR-600 MICROPHONE CONTROL

        There are functions that can be utilized from the 600 mic or
        remotely accessed. This section will focus on functions accessed
        via the microphone.

17.1    DSQ DESCRIPTION

        To operate DSQ, it is required to have the optional DTMF Unit
        (EJ-8U) and a 16 Tone DTMF Pad Microphone ((EMS-3Z) Standard with
        the US version, Optional with the European version).

        The DSQ is divided into two primary functional groups:

          1. Code Squelch
          2. DSQ Paging

17.2    CODE SQUELCH

        Code Squelch allows the squelch to be opened when the DR-600T/E
        receives a pre-designated three (03) digit code as programmed into
        any of the three group DSQ channels 1-3.

17.3    PROGRAM DSQ CODE

        The DSQ is an abbreviated name for DTMF Squelch Control. This
        feature is used to DE-Code DTMF tones to open (or keep closed) the
        DR-600T/E squelch, and allow for receiving a transmission. This
        function is used to control your DR-600 remotely via a hand held
        radio. After  the following steps are taken, your radio will only
        accept commands after a special combination of codes are sent.

          1. Select VFO mode, and set desired frequency.

          2. Make sure "Lock" switch on Mic is off (Right), and
             "Remote/DTMF" switch is in "Remote" position (Left).

          3. Enter C10 on the Touch Tone Pad of the Mic. The frequency
             indicator on the main band (VHF/UHF) will blink on and off
             repeatedly.

          4. On the Touch Tone Pad of the Mic enter a channel selection
             (one numerical digit 1-4), and an access code (three numerical
             digits, any selection from 000 to 999).

          Immediately after entering the third digit of your access code
          (total of four digits, including the channel selection) the
          DR-600T/E will return to VFO mode.


          5. Enter C12 on the Touch Tone Pad of the Mic. Flashing DSQ
             indicator will appear.

          6. Push the PTT key on the Mic, or the "VFO" key on the front
             panel. The DSQ indicator will stop flashing.

          7. Push the "FUNC" key, and then the MHz Up key on the front
             panel. There will be a confirming tone, and the DSQ will begin
             flashing (on and off) again.

          8. To cancel the Remote Control Function, enter C12 on the Mic
             and press the MHz Down key. DSQ indicator will disappear.

        At this point the Remote Control Function is programmed into the
        DR-600T/E, and can be controlled from a remote unit. It is
        recommended that this programming be stored in every memory channel
        that you may want to work remotely. To maintain Remote Control of
        the DR-600T/E it is necessary to  have the flashing DSQ displayed
        on the LCD. If you change to modes (VFO or Memory), or memory
        channels that DON'T have a flashing DSQ programmed YOU WILL LOSE
        REMOTE CONTROL. The DTMF 3 digit codes for Remote Controlling are
        the same as used when controlling the DR-600T/E from the Touch Tone
        Pad   on the Mic.

17.4    DSQ PAGING

        DSQ Paging has three functions:

          1. Group

             This allows the user to Page all the members of a
             predesignated group. A  group is identified by seven (07)
             digits.

                   GROUP CODE........3 digits
                   A CODE DELINEAR...1 digit (* on DTMF pad)
                   SELF STATION CODE 3 digits

             When the group pager function is activated,stations with the
             same group code can communicate with all members of the group.
             The DR-600T has three channels for group codes. This allows
             the operator to have access to three different groups.

                                   ***NOTE***

             The "*" As a Group Separator DSQ has reserved the "*" mark as
             a separator between different DSQ channels. The "*" CANNOT be
             used as any digit of a  three digit DSQ Code.

          2. Individual

             This allows the user to Page one pre-designated individual. An
             individual is identified by seven (07) digits.

                    REMOTE STATION CODE...3 digits
                    A CODE DELINEAR.......1 digit (* on DTMF pad)
                    SELF STATION CODE.....3 digits



             When the individual pager function is activated, an
             individuals with the pre-designated individual code can
             communicate with the DR-600T/E operator. The DR-600T/E has one
             channel for individual codes.

                                   ***NOTE***

             The "*" As a Group Separator DSQ has reserved the "*" mark as
             a separator between different DSQ channels. The "*" CAN NOT be
             used as any digit of a three digit DSQ Code.

          3. Private Paging Within A Group

             This allows the user to Page one individual within a
             pre-designated group. An individual is identified by six (06)
             digits.

                    GROUP CODE.............................3 digits
                    FIRST DIGIT OF A REMOTE STATION CODE...1 digit
                    A "*"..................................1 digit
                    FIRST DIGIT OF THE PRE-DESIGNATED
                    SELF STATION CODE......................1 digit


                              ***NOTE***

        The "*" As a Group Separator DSQ has reserved the "*" mark as a
        separator between different DSQ channels.  The "*" CANNOT be used
        as any digit of a three digit DSQ Code.

             indicator will begin to flash confirming the Code Squelch
             feature selected.

          3. Press the PTT, DSQ stops flashing.


          4. While the DSQ indicator is flashing, press the Mhz Up key to
             select Paging, Group, or  Individual within a Group. After the
             proper selection has been made.

          5. Press PTT on the microphone. The DSQ indicator will stop
             flashing.

                                   ***NOTE***

          When the proper DSQ mode has been selected, the DR-600T/E will
          only receiver transmissions from another source when the proper
          DSQ codes are sent. Those DSQ codes will open the squelch on the
          DR-600T/E and allow a received signal to be monitored.

17.7    OPERATING DSQ PAGING AND SQUELCH

        Operating DSQ paging and squelch will allow the originating
        DR-600T/E to open the squelch of a remote transceiver (compatible
        with the DR-600T/E).

          1. Select the DSQ feature desired on the originating DR-600T/E.
             DSQ will transmit the 3, 7, or 6 digits of any selected group
             code.

          2. Every time the PTT is depressed, the appropriate DSQ codes (as
             per selected feature) will be transmitted automatically.

17.8    EXAMPLES OF DSQ TRANSMISSIONS

        When DSQ feature is selected, one of the Group Code (DSQ channels
        1-3) will be automatically transmitted. You can choose which group
        code (DSQ channel) is transmitted by entering C11 on the Mic and
        using the MHz Up/Down key to select the desired channel. When the
        PTT is depressed, the chosen DSQ code will be automatically
        transmitted. Any compatible transceiver with the proper programming
        will open squelch.

        Example:

                Operation                Channels
          ---------------------------------------------------------
          Self Station Code,    DSQ channel No.0          085  DSQ1
          Group Codes,          DSQ channel No.'s 1 - 3   147  DSQ1
                                                          258  DSQ2
                                                          369  DSQ3
          Remote Station Code,  DSQ channel No. 4         456  DSQ4

          When G DSQ feature is selected, the three digits of the selected
          DSQ channel (1-3) (Group Code), the "*" sign, and the three
          digits of DSQ 0 (Self Station Code), are transmitted
          automatically when the PTT is depressed.  Any compatible
          transceiver with the proper programming will open squelch.

          PG DSQ - Individual within a Group Paging

          When PG DSQ feature is selected, the three digits of the selected
          DSQ channel (1-3) (Group Code), the first digit of DSQ channel 4
          (Remote Station Code), the "*" sign, and the first digit of DSQ
          channel 0 (Self Station Code).  Any compatible transceiver with
          the proper programming will open squelch.

17.9    USING THE WILDCARD

          DSQ has reserved the "#" mark as a wildcard. The wildcard allows
          for combining of groups. If the first (or first and second) digit
          of a several group codes are the same, you can replace the second
          and third digits (or just third digit) with a "#" mark, and thus
          transmit to all those groups.

          Ex: Group Code (DSQ Channels 1-3)

                Channel        DSQ Code      Wildcard
                   1             123           12#
                   2             124           12#
                   3             156           1##

          In this example, the user could contact two (or all three) groups
          together, not separately as would be the case if "#" as wildcard
          was not used.

17.10   CHANGING VFO FREQUENCY

        There are two methods of changing the VFO frequency of the main
        band (VHF or UHF) directly from the microphone.

        Stepping by MHZ

          1. Enter the programmed three digit access code.

          2. Enter C08 to go up 1 MHz or C09 to go down 1 MHz.

        Direct Entry

          1. From the VFO mode, enter the new frequency desired. You must
             enter all 6 digits of the frequency If Step is set at 12.5 kHz
             you will only need to enter 5 digits to change the VFO
             frequency.

18      ADDITIONAL FUNCTIONS AND OPERATIONS

        This section will cover all all operations and functions not
        previously described.





18.1    SIMULTANEOUS RECEIVING

        Among the many useful features of the DR-600T/E is the ability to
        receive on both bands at the same time

          1. Simply select the desired receiving frequencies on each band.
             Ensure that the MUTE function is not active on either band.

18.2    FULL DUPLEX OPERATION

        Among other features of the DR-600T/E is the ability to operate in
        the "Full Duplex" mode.  Full Duplex is similar to a telephone,
        where both parties can speak and listen simultaneously on two
        difference channels.

          1. Select VFO and set the desired frequency on each band. Either
             band may be used to transmit. The selected Main Band will be
             the transmitting band. The sub-band will be the receiving
             band. In this mode you speak on the Main Band and listen on
             the sub-band. Avoid repeater frequencies. Restrict full duplex
             operation to established simplex frequencies only.

18.3    ABX (Automatic Band Exchange)

        This function automatically selects whichever band is active (The
        presence of a signal) as the Main Band. To select the ABX Function;

          1. Select VFO and set desired frequency.

          2. Press FUNC key. The ABX indicator will appear on the LCD
             display.

          If the microphone PTT switch is pressed while ABX has switched to
          the sub band, the ABX function is cancelled and the sub-band
          becomes the main band. If a priority function is active on the
          sub-band it will be inactive when ABX switches to the main band.
          Priority will resume when ABX returns to the sub-band.

18.4    MUTE

        The MUTE function permits temporary silencing of either band. To
        select the MUTE Function;

          1. Press the MUTE key once for UHF, twice for VHF, three times
             for cancelling MUTE.

18.5    LOCK

        This function prevents unintended function changes by locking out
        all functions except the main Power switch, and the microphone PTT
        switch. To select the LOCK Function;

          1. Press the "FUNC" key and then the (LOCK) key to enable. To
             disable LOCK, follow step 1 again.






18.6    DIM

        The DIM function allows selection of two different LCD display
        panel brightness levels. To change LCD brightness level;

          1. Press the "FUNC" key, then the (DIM) key. Repeated pressing of
             those keys will raise and lower the brightness level of the
             LCD.

18.7    CANCEL

        Some mistaken operations may be corrected with the CANCEL Function.

19      CROSS BAND

        To manually place your DR-600 into Cross Band Repeat mode, you must
        modify your radio. These steps are straightforward, easy to
        perform, so take your time. We have broken this procedure into
        small distinct sub-sections called:

                 o BEGIN CROSS BAND REPEATER MODIFICATION
                 o FINISH CROSS BAND REPEATER MODIFICATION
                 o RADIO RESETTING
                 o CROSS BAND REPEATER MODIFICATION

19.1    BEGIN CROSS BAND REPEATER MODIFICATION

        The DR-600T/E is capable of operating as a Cross Band Repeater. The
        DR-600T/E will receive a transmission on one band (VHF or UHF) and
        re-transmit on the other band.

        It is necessary to perform a simple factory authorized modification
        (clipping a wire) to open the Cross Band Repeater function.  After
        performing that modification, accessing Cross Band Repeater is
        accomplished through the front panel, or a remote unit.

          1. Remove power source to the radio.

          2. Remove four (04) screws holding the front panel to the unit
             main body. There are two screws on the right-hand side and two
             screws on the left-hand side of the front panel. The front
             panel can now be removed from the main body.

          3. To separate the front panel from the main radio chassis,
             carefully unplug the cable in back of the front panel.

          4. Remove two (02) screws holding the cover plate to the back of
             the front panel.

          5. Carefully remove the back cover of the front panel, using a
             narrow blade, flat tip screw driver. Only slight pressure
             is required.

          6. Cut or remove the "BLUE WIRE" Loop located on the exposed PC
             board. Go to "FINISH CROSS BAND REPEATER MODIFICATION".





19.2    FINISH CROSS BAND REPEATER MODIFICATION

          7. Gently refit back cover to the front panel.

          8. Insert the two (02) screws and secure.

          9. Connect cable from main radio chassis to the front panel.

         10. Refit front Panel to Main Body.

         11. Attach front panel with four (04) small screws.

         12. Go to "RADIO RESETTING".

19.3    RADIO RESETTING

          1. Press and hold the "FUNC" key.  While holding the "FUNC" key
             push the "Power" key on the front panel.  The LCD will display
             145.00 (VHF) and 445.00 (UHF), and you can now access Cross
             Band Repeat.

        After performing the modification (described above), and resetting
        the radio, Cross Band Repeat can be accessed directly through the
        front panel or by remote control. For remote control, go to this
        section.

        To engage cross band repeater function:

          1. Press and hold the "FUNC" key, then press the "VHF" key.

        To disengage cross band repeater function:

          1. To disengage Cross Band Repeater function, press and hold the
             "FUNC" key, then press the UHF key.

20      MOBILE ANTENNA INSTALLATION

        Connect the antenna for VHF to the VHF terminal located in the rear
        of the DR-600. Connect the antenna for UHF to the UHF terminal
        located in the rear of the DR-600. When using a single dual-band
        antenna, a DUPLEXER is required. The use of 50 ohm coaxial cable is
        required for all antenna installations. Mobile antennas required an
        appropriate mounting base for proper installation and operation.
        Please refer to the  antenna  manufacturers manual for the proper
        installation and mounting information. Antenna accessories are NOT
        available from ALINCO.
