REPEATER AND DUPLEX OPERATIONS

■ Accessing a repeater

When using a repeater, the transmit frequency is shift-
ed from the receive frequency by the frequency offset
(p. 38). This is called duplex operation. It is convenient
to program repeater information into memory channels
(p. 21).
q Set the receive frequency (the repeater output fre-
quency).
• For only USA version of IC-V80:
When the Auto Repeater function is ON, steps w
and e are not necessary.
w Push [FUNC](M), and then push [DUP](4) several
times to select minus duplex or plus duplex. ( "–" or
"+")
e Push [FUNC](M), and then push [TONE](1) several
times to turn ON the subaudible tone encoder, de-
pending on the repeater requirements.
• " " appears.
• The subaudible tone frequency can be set in the Set
mode.
r Hold down [PTT] to transmit.
• The displayed frequency automatically changes to the
transmit frequency (repeater input frequency).
• If "OFF" appears, confi rm that the frequency offset is cor-
rectly set.
t Release [PTT] to receive.
y Hold down [MONI] to check whether you can directly
receive the signal from the other station.
• When the other station's signal can be directly received,
move to a non-repeater frequency to use simplex. (duplex
OFF)
For only USA version of IC-V80:
Auto Repeater function uses standard repeater tone
frequencies and frequency offsets.
