REPEATER AND DUPLEX OPERATIONS

■ Subaudible tones

Some repeaters require subaudible tones to access.
Subaudible tones are superimposed over your normal
signal, and must be set in advance.
q Push [FUNC](M), and then push [SET](8) to enter
the Set mode.
w Push [Y] or [Z] to select the repeater tone item (rt).
e Rotate [VOL] to select the desired subaudible tone
frequency.
r Push [# ENT] to exit the Set mo
• Available subaudible tone frequencies

Tone scan:
If you don't know the subaudible tone used for a repeater, the
tone scan is convenient for detecting the tone frequency.
➥ Push [FUNC](M), and then push [T.SCAN](3) to
start a tone scan.
• See page 32 for details of the Tone Scan function.
D 1750 Hz TONE
To access some European repeaters, the transceiver
must transmit a 1750 Hz tone burst.
For only IC-V80E
➥ Quickly push [PTT] once, then immediately hold
down [PTT] again for 1 or 2 seconds.
For other transceivers
NOTE: First, set the DTMF TX key to "dmt.t" in the Set
mode. (p. 34)
➥ While holding down [PTT], hold down either the [Y]
or [Z] for 1 or 2 seconds.
■ DTCS encoder (Only TX)
The DTCS encoder superimposes the selected DTCS
code over your transmitted signal.
q Push [FUNC](M), and then push [SET](8) to enter the Set
mode.
w Set the DTCS code and polarity, in the same way you
set the DTCS squelch. (p. 30)
• You can set the DTCS transmit and receive polarity, but
the DTCS encoder affects only transmit.
e Push [# ENT] to exit the Set mode.
r Push [FUNC](M), and then push [TONE](1) several
times, until both " " and " " appear.
D
• The DTCS encoder activated.
