OTHER FUNCTIONS
■
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 repeater.
q
Set the desired frequency or memory channel to be
checked for a tone frequency or DTCS code.
w
Push and hold
[TONE](7)
for 1 sec. several times to acti-
vate the repeater tone, tone squelch or DTCS squelch.
(TONE, TSQL or DTCS)
• Rotating

lects the tone functions.
e
Push and hold
[T.SCAN](9)
for 1 sec. to start the tone
scan.
• To change the scanning direction, rotate

.
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. 96) when a tone frequency or DTCS code is detected.
• The decoded tone frequency is used for the repeater tone fre-
quency when the tone squelch is OFF.
• The decoded tone frequency is used for the tone squelch fre-
quency (CTCSS TONE) when the tone squelch is ON.
• The decoded DTCS code is used for the DTCS code when the
DTCS squelch is ON.
t
Push
[VFO]
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 temporary operation only. The stored tone
setting in memory or call channel won’t be changed.
