REPEATER OPERATION

■ Duplex operation

D Setting the frequency offset
q Push [FUNC](M), and then [SET](8) to enter the Set mode.
w Push [] or [] to select the offset item.
• "±" blinks, and the current frequency offset appears.
e Rotate [VOL] to select the frequency offset.
• The offset is selected in the
same step as the frequency
tuning step.
• The unit of the frequency
offset is "MHz."
r Push [# ENT] to exit the Set mode.
D Setting the duplex direction
➥ Push [FUNC](M), and then [DUP](4) to select "–" (nega-
tive offset) or "+" (positive offset).
• "–" or "+" indicates the transmit frequency is shifter up (+) or
down (–) from the receive frequency.
• Blinking "–" or "+" indicates the reverse duplex function is ON,
as described to the right.
• Example— When the offset frequency is 0.6 MHz

0.6 MHz offset
While transmitting
For the U.S.A. version:
The auto repeater function has priority over the manual
duplex setting. If the transmit frequency changes after
setting, the auto repeater function may have changed the
duplex setting. Turn the auto repeater function OFF to
prevent this (p. 23).
D Reverse duplex function
When the reverse duplex function is ON, the receive and
transmit frequencies are reversed. The function can be set in
the Set mode.
q Push [FUNC](M), and then [SET](8) to enter the Set mode.
w Push [] or [] to select the reverse duplex function item
(REV).
e Rotate [VOL] to turn the function ON or OFF.
r Push [# ENT] to exit the Set mode.
Each receive and transmit frequency is shown in the table
below, with the following configurations;
Input freq. : 145.300 MHz
Reversed
Direction : – (down)
Offset : 0.6 MHz
• "–" or "+" blinks when the re-
verse duplex function is ON.
