BASIC OPERATION
Duplex communication uses two different frequencies for trans-
mitting and receiving. Generally, duplex is used in communi-
cation through a repeater, some utility communications, etc.
During duplex operation, the transmit station frequency is
shifted from the receive station frequency by the offset fre-
quency. Repeater information (offset frequency and shift di-
rection) can be programmed into memory channels. (p. 16)
D D Setting [
q Push [SET•LOCK] to enter set mode.
w Push [SET•LOCK] or [S.MW•MW] several times until the
duplex direction setting item “OFF
dP ,” “DUP– dP ” or “DUP+
dP ” appears.
e Rotate [DIAL] to select the duplex direction, “DUP– dP ” or
“DUP+ dP .”
r Push [SET•LOCK] once to advance to the offset frequency
setting item.
t Rotate [DIAL] to set the desired offset frequency within
0.000–1000.000 MHz range.
• The tuning step, selected in VFO mode, is used for setting.
• Push [V/MHz• SCAN] then rotate [DIAL] to change the fre-
quency in 10 MHz steps, or push again then rotate [DIAL] to
change the frequency in 1 MHz steps. (Each push toggles
1 MHz, 10 MHz or selected tuning steps.)
y Push [TS•MODE] or any key below the display to exit set
mode.

quency
(repeater input frequency) directly.
