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
1. Push [SET] to enter the Set mode.
• A Set mode item is displayed.
2. Repeatedly push [SET] to select “OFFSEt.”
3. Rotate [DIAL] to set the frequency offset.
• “DUP” blinks.

3. Rotate [DIAL] to set a duplex direction.
• OFF: The receive and transmit frequencies are the

• –:
The transmit frequency shifts down from the
receive frequency by the offset amount.
• +:
The transmit frequency shifts up from the

Duplex operation
1. Hold down [MONI] to listen to the transmit
frequency to check whether another station is
transmitting on it or not.
•
The frequency shifts by the offset amount.
2. Operate in the same way as a simplex call,
alternately transmit and receive.
NOTE for the USA version:
The Duplex mode is automatically canceled
when the Auto Repeater function (p. 4-5) is
ON, and the operating frequency is set out of the
repeater output frequency range.
