10-4
The Duplex operation shifts the transmit frequency
up or down from the receive frequency by an offset
amount

Setting the frequency offset
NOTE:
The frequency offset cannot be changed
when using the DR function
MENU > DUP/TONE >
Offset Freq
1 Push [MENU]
2 Select “DUP/TONE”
3 Select “Offset Freq”
4 Rotate [DIAL] to set the offset

Duplex operation
D
Duplex operation
1 Hold down [SQL] to listen to the transmit
frequency to check whether another station is
transmitting on it, or not
•
The shifted transmit frequency is displayed
2 Operate in the normal way
L
In the same way as a simplex call, alternately
transmit and receive
NOTE:
When the
Auto Repeater
function is
ON, and the operating frequency is set out of the
Repeater output frequency range, the duplex mode
is automatically cancelled
(MENU > Function >
Auto Repeater
)
TIP:
If the offset value causes the transmit
frequency to be out of the band, “OFF BAND” is
displayed when you push [PTT], and transmit will
be inhibited (p10-5)
