ICOM 325300 Manuale Utente

N Tone scan

The transceiver can detect the subaudible tone frequency
and DTCS code in a received signal. By monitoring a signal
that is being transmitted on a repeater input frequency, you
can determine the tone frequency required to access the re-
peater.

q Set the desired frequency or memory channel to be

checked for a tone frequency or DTCS code.

w Push and hold [TONE](0) for 1 sec. repeatedly to activate

the repeater tone, tone squelch or DTCS squelch. (T,
T SQL or DTCS)

e Push and hold [T.SCAN](#) for 1 sec. to start the tone

scan.

• To change the scanning direction, rotate [DIAL].

r When the tone frequency or DTCS code is decoded, the

set mode contents are programmed with the frequency or
code.

• The tone scan pauses for the set period in scan pause timer

(p. 47) when a tone frequency or DTCS code is detected.

• The decoded tone frequency is used for the repeater tone fre-

quency when any tone setting, such as repeater tone or tone
squelch is OFF.

• The decoded tone frequency is used for the tone squelch fre-

quency when the tone squelch is ON.

• The decoded DTCS code is used for the DTCS squelch code

when the DTCS squelch is ON.

Tone scan for tone squelch

t Push [V/M/C] to stop the scan.

• If the scan is cancelled before the transceiver detects the tone

or code, the set mode contents are not changed.

• The detected tone is used for temporary operation only.

The stored tone setting in memory or call channel won’t be
changed.

OTHER FUNCTIONS

NOTE: Tone frequency is over-written automatically when
it corresponds with the scanning tone frequency in tone
squelch mode. However, it is not over-written in memory or
call channel mode.
