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.

     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.

     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

     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:

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.

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

4. Enter telephone number and any required codes up to a maximum
     of 18 digits.

5. Press the VFO or PTT switch on the microphone to store phone
     number or DTMF codes.

    AUTODIALER TRANSMITTING

Remember that the optional DTMF Unit (EJ-8U) is required for
Autodialer operation.

2. Select the appropriate autodialer number. Select channel by
     using the Mhz Up/Down key on the front panel.

3. Press the "FUNC" key and then the "SKIP" key. The autodialer
     memory channel selected will be erased of all numbers and
     codes.

***NOTE***

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
hand held radio remotely. This is achieved simply by performing the
following.

ENABLE

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

2. Press the "D" key followed by 99. This enables Cross Band
     repeat.

DISABLE

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

2. Press the "D" key followed by 01. This disables Cross Band
     repeat.

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.

     with same codes programmed will open squelch, and receive
     transmission.

17.6    SELECTING DSQ MODE

The DSQ mode consists of four features; three paging
(Group,Private, and Individual within a Group) and Code Squelch.
Each feature is displayed on the LCD when selected.

LCD Display   DSQ Mode Feature

DSQ: Code Squelch
P DSQ:Private Paging
G DSQ:Group Paging
PG DSQ:       Individual within a Group Paging
Indicator Off:No DSQ Setting

Here is how to make the appropriate selection:

1. Set the "Lock" switch on the Mic to the Unlocked position
     right), and the "Remote/DTMF" switch to the remote position
     (left).

2. Enter "C12" on the Touch Tone Pad on the Mic. The "DSQ"
     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:

OperationChannels
---------------------------------------------------------
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

P DSQ - Private Paging

When P DSQ feature is selected, the three digits of DSQ channel 4
(Remote Station Code), the "*" sign, and the three digits of DSQ
channel 0 (Self Station Code), are transmitted automatically when
the PTT is depressed. Any compatible transceiver with the proper
programming will open squelch.

G DSQ - Group Paging

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)

ChannelDSQ 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.
