REPEATER AND DUPLEX OPERATIONS

Duplexoperation
The Duplex operation shifts the transmit frequency up or
down from the receive frequency by an offset amount.
NOTE:
The frequency offset cannot be changed in the DR
function.
Foryourreference:
If the offset value will cause the transmit frequency
to be out of the band, “OFF BAND” appears on the
display when [PTT] is pushed, and transmit will be
inhibited. (p. 11-5)
D Settingthefrequencyoffset
Touch the Memory channel number. q
• Opens the Mode setting window.
Touch [VFO]. w
• Selects the VFO mode.
Touch [MENU]. e
Touch “Offset Freq.” r
(DUP/TONE... > OffsetFreq)
Touch the numbers to enter the desired offset. t
(Example: 0.700.00 MHz)
• Between 0.000.00 and 59.99500 MHz.
• The selected tuning step in the VFO mode is used when
setting the frequency offset.
• If desired, touch “CE” to delete the entry.
Touch [ENT] to set the offset. y
• Exits from the “Offset Freq” screen.
• Sets the offset.
Touch [MENU]. u
• Closes the Menu screen.

Touch the Function group icon one or more times. q
• Selects the F-3 menu.
Touch [DUP]. w
• Opens the duplex direction setting window.
Touch the desired option. e
• OFF: For simplex operation (the receive and transmit
frequencies are the same).
• DUP–: The transmit frequency shifts down from the re-
ceive frequency by the offset amount.
• DUP+: The transmit frequency shifts up from the receive
frequency by the offset amount.
• After setting, “DUP–” or “DUP+” appears.
D Duplexoperation
Touch [MONI] to listen to the transmit frequency to q
check whether another station is transmitting on it,
or not.
• The transceiver transmit frequency appears on the dis-
play.
Touch [MONI] again to turn OFF monitoring, and w
then operate in the normal way.
NOTE:
When the Auto repeater is ON, and the operating
