BASIC OPERATION

■ Repeater operation

When using a repeater, the transmit frequency is shifted from
the receive frequency by the frequency offset (p. 33). This is
called duplex operation. It is convenient to program repeater
information into memory channels (p. 28).
434.700 MHz
439.700 MHz
Station A
Set the receive frequency (repeater output frequency).
q
Set the shift direction of the transmit frequency in the Quick
w
Menu (DUP– or DUP+; see next page for details).
• When the Auto Repeater function is in use (only U.S.A., Canada
and Korean versions), this selection and step e are not necessary.

439.700 MHz
Station B
If desired, activate the subaudible tone encoder in the
e
Quick Menu (see next page for details).
"TONE" appears
r Hold down [PTT] to transmit.
• The displayed frequency automatically changes to the transmit
frequency (repeater input frequency).
• If "OFF BAND" appears, check the frequency offset and shift
direction. (p. 33)
While receiving
t Release [PTT] to receive.
y Hold down [SQL] to check whether the other station's
transmit signal can be directly received or not.
• When the other station's signal can be directly received, move
to a non-repeater frequency to use simplex (duplex OFF).
U.S.A., Canada and Korean versions:
Auto repeater function uses standard values of the re-
peater tone frequency and offset frequency.
