Repeater Operation
1. Press the [FUNC] key momentarily, then rotate the SELECT knob, as needed, until
Multi Function Row “d” [RPT, REV, VOX] appears on the display.
2. Press the [A](RPT) key to activate repeater operation. One press of the [A](RPT) key
will have set the transceiver for “Minus Shift” operation. In this situation, you will ob-
serve the “–” indicator on the display. The transmitter frequency will be shifted down by
a default value so as to access the repeater input frequency. If your repeater uses a posi-
tive shift (instead of negative), press the [A](RPT) key again; the “+” indicator will
replace the “–” indicator on the display. Set the transceiver’s receiver to the repeater
output (downlink) frequency. Close the PTT switch and speak into the microphone. You
will observe that the transmitted frequency has shifted according to the setting of the

to return to the Receive mode.
3. If the default repeater shift is not appropriate for the majority of the repeaters your area,
it may be set independently for each band. To
change the default repeater shift:

Ÿ Rotate the DIAL knob to select the desired shift
frequency.
Ÿ When done, press and hold in the [FUNC] key
for one second to save the new setting and exit
to normal operation.

4. If your repeater uses controlled access (using either CTCSS or DCS), press the [FUNC]
key momentarily, then rotate the SELECT knob one click clockwise to cause Multi
Function Row “e” [TON, – – –, TDCH] to appear on the display. Now select the appropri-
ate tone access system:

ate tone access system:
Ÿ Press the [A](TON) key to activate the CTCSS tone encoder, which provides a
subaudible repeater access tone. One press of the [A](TON) key will activate the
CTCSS tone encoder. In this situation, you will observe the “TEN” indicator on the
display. If you press the [A](TON) key repeatedly, you will observe “TSQ” (CTCSS
Encode/Decode), “DEN” (Digital Coded Squelch, Encode), followed by “DCS” (Digi-
tal Coded Squelch, Encode/Decode). One additional press will disable all repeater-
access tone systems. See the next section for a discussion of DCS operation.
