FM repeater operation
A repeater receives your radio’s signals and
simultaneously retransmits them on a different
frequency to provide a greater communication range.
When using a repeater, the transmit frequency shifts
from the receive frequency by an offset amount. You
can access a repeater using the split function.
1. Select the desired operating band. (p. 3-2)
(Example 28 MH band)
2. Rotate
MAIN DIAL
to set the operating frequency.
(Example 2 .650.00 MH )
3. Select the FM mode.
4. Hold down
SPLIT
for 1 second.
• Turns the Split function ON.
• Turns the Tone function ON and “TONE” is displayed.
• Displays the transmit frequency.

You can check the tone frequency by receiving the
repeater’s input frequency and tone scanning. To
receive the input signals, the transceiver detects
the subaudible tone frequency using the tone scan
function.
1. Touch [T-SCAN].
• The scan starts, and then stops when the matching
tone frequency as the repeater is received.
