Icom IC-T70E [78/96] Tone scan
New2001
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 repeater tone
Tone scan for tone squelch
Tone scan for DTCS 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 wont be
changed.

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.
