REPEATER AND DUPLEX OPERATION
4-2
When using a repeater, the transmit frequency is
shifted from the receive frequency by the frequency
offset. (p. 9-2) This is called duplex operation. It
is convenient to program repeater information into
memory channels.
1. Set the receive frequency (the repeater output
frequency).
•
For only the USA version:
When the Auto Repeater function is ON, steps
2 and 3 are not necessary.
2. Push [FUNC], and then push [DUP] several times
to select minus duplex or plus duplex. ( “–” or “+”)
3. Push [FUNC], and then push [TONE] several
times to turn ON the subaudible tone encoder,
depending on the repeater requirements.
• “ ” is displayed.
L
The subaudible tone frequency can be set in
the Set mode.
4. Hold down [PTT] to transmit.
• The displayed frequency automatically changes
to the transmit frequency (repeater input
frequency).
L
If“OFF”isdisplayed,confirmthatthefrequency
offset is correctly set.
5. Release [PTT] to receive.
6. Hold down [MONI] to check whether you can
directly receive the signal from the other station.
L
When the other station’s signal can be directly
received, move to a non-repeater frequency to
use simplex. (duplex OFF)
For only the USA version:
Auto Repeater function uses standard repeater tone
frequencies and frequency offsets.
