Subaudible Tone Encoder - Icom IC-G80 Instruction Manual

■ Subaudible tone encoder

Some repeaters require subaudible tones to be accessed.
Subaudible tones are superimposed over your transmitted
signal and must be set first.
q Push [FUNC](M) then [SET](8) to enter the Set mode.
w Push [] or [] to select the Repeater tone encoder item.
(rt)
e Rotate [VOL] to select the subaudible tone.
[VOL]
r Push [# ENT](MN.W) to exit the Set mode.

REPEATER OPERATION
D Tone information
Some repeaters require a different tone system to be ac-
cessed.
DTMF TONES
While pushing [PTT], push the desired DTMF keys, [0] to [9],
[MONI](A), [](B), [](C), [
to transmit their assigned DTMF codes.
• The transceiver has 16 DTMF memory channels (p. 27).
DTCS CODES
Push [FUNC](*), and then [TONE](1) one or more times to
activate the DTCS encoder, and then push [PTT].
• " " and " " appear.
D
• The specified DTCS code is superimposed over your transmitted
signal.
• See page 24 for DTCS code setting details.
✔ CONVENIENT!
Tone scan function:
If you don't know the subaudible tone or DTCS code used for
a repeater, the tone scan is convenient for detecting it.
➥ Push [FUNC](M), and then [T.SCAN](3) to start a tone
scan.
• When the required tone frequency or DTCS code is detected, the
scan pauses, and it is temporarily set.
• See page 26 for Tone Scan function details.
