Subaudible Tones - Icom ic-U80 Instruction Manual

■ Subaudible tones

To be accessed, some repeaters require subaudible tones.
Subaudible tones are superimposed over your normal signal,
and must be set first.
q Push [FUNC](M) then [SET](8) to enter the Set mode.
w Push [p] or [q] to select the repeater tone item. (rt)
e Rotate [VOL] to select the desired subaudible tone.
[VOL]
r Push [# ENT] to exit the Set mode.

REPEATER OPERATION
D Tone information
To be accessed, some repeaters require a different tone system.
DTMF TONES
While pushing [PTT], push the desired DTMF keys, [0] to [9],
[MONI] for A, [p] for B, [q] for C, [VFO/MR/CALL] for D, [M] for
E, and [# ENT] for F, to transmit their assigned DTMF codes.
• The transceiver has 16 DTMF memory channels (p. 36).
1750 Hz TONE
To access some European repeaters, the transceiver must
transmit a 1750 Hz tone burst.
While pushing [PTT], hold down either the [p] or [q] for 1 or
2 seconds. See page 37 for details.
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 33 for DTCS code setting details.
✔ CONVENIENT!
Tone Scan function:
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 [T.SCAN](3) to start a tone scan.
• When the required tone frequency is detected, the scan pauses,
and the tone frequency is temporarily set.
• See page 35 for details of the tone scan function.
