REPEATER AND DUPLEX OPERATIONS

Duplex operation

The Duplex operation shifts the transmit frequency
up or down from the receive frequency by an offset
amount.

D Setting the frequency offset

NOTE: The frequency offset cannot be changed
when using the DR function.
DUP/TONE... > Offset Freq
1. Push [MENU].
2. Rotate [DIAL] to select "DUP/TONE...," then push
[ï].
3. Select "Offset Freq," then push [ï].
4. Rotate [DIAL] to set the offset.
(Example: 0.700.00 MHz)
L Set to between 0.000.00 and 59.99500 MHz.
L The selected tuning step in the VFO mode is used to
set the offset.
5. Push [ï] to set the offset.
6. Push [MENU].
• Returns to the standby screen.
TIP: If the offset value will cause the transmit
frequency to be out of the band, "OFF BAND" is
displayed on the display when [PTT] is pushed, and
transmit will be inhibited. (p. 8-5)
D Setting the duplex direction
1. Push [QUICK].
2. Rotate [DIAL] to select "DUP," then push [ï].
3. Select the offset direction, then push [ï].
• OFF: For simplex operation (the receive and
transmit frequencies are the same).
• DUP–: The transmit frequency shifts down
from the receive frequency by the offset
amount.
• DUP+: The transmit frequency shifts up from the
receive frequency by the offset amount.
• Displays "D–" or "D+."
D Duplex operation
1. Push [MONI] to listen to the transmit frequency to
check whether another station is transmitting on
it, or not.
• The transceiver transmit frequency is displayed on the
display.
2. Push [MONI] again to cancel monitoring.
3. Operate in the normal way.
NOTE: When the Auto repeater is ON, and the
operating frequency is set out of the repeater output
frequency range, the duplex mode is automatically
cancelled.
