Note
The offset frequency and automatic repeater band could be
programmable by factory or dealer/service center.

5-7-3 Reverse Function

Some repeaters utilize a " Reverse Pair ", i,e, the transmit/receive
frequencies are exactly the reverse of another repeater. For example
repeater A uses 146.000 for a transmit frequency (INPUT) and 146.000
for a receiver frequency (OUTPUT). Repeater B might use 146.00 for a
receiver frequency. It would be inconvenient to have to reprogram the
transceiver each time you use these repeaters.
Press F key momentarily. The F indicator should light in the display.
Press the SHFT/REV key within 10 seconds of pressing the F key.
The REV function is active.
To return to normal press the SHFT/REV key again. The REV indicator
will be turned off.
This function is also useful to check the input frequency of the repeater
so that you can determine if you are within range for simplex
communications.

5-7-4 Tone Operation

Some repeaters require the use of a control signal to activate the
repeater. Several different methods are currently in use.
Sub-audible tones are sometimes used. The transceiver provides two
types of subaudible tone, CTCSS and DCS. There are 50 selectable
CTCSS tones and 106 selectable DCS codes for users.
A repeater access tone is also used in transmit. Press and hold the PTT
key to transmit, then press the microphone CALL key will generate a
repeater access tone.During the repeater access tone being transmitted,
the CTCSS/DCS sub-audible tone is muted.
Repeater Access Tone Selection
1. Press the F key for longer than 1 second when the transceiver not in
CTCSS/DCS mode, then press the TONE/DUAL key within 10
seconds. The current repeater access tone will show on the display.
2. Rotate the tuning control or press the microphone UP/DN switches to
select the desired repeater access tone (1450,1750 or 2100 Hz)
3. Press any front panel key to return to the normal display.

5-7-5 CTCSS Tone Selection

1. Press the F key for longer than 1 second when the transceiver in
CTCSS mode. The F indicator will begin to flash. Press the
TONE/DUAL key within 10 seconds of pressing the F key. The current
CTCSS tone frequency will show on the display.
2. Rotate the Tuning control or press the microphone UP/DN switches to
select the desired CTCSS tone frequency.
3. Press any front panel key to return to the normal frequency display.
