Tone/DTCS squelch
q
Set a desired operating frequency, and then set a
CTCSS tone or DTCS code.
w
Push and hold
[TONE]
(0) for 1 sec. repeatedly to activate
the tone or DTCS squelch. (T SQL or DTCS)
• Subaudible tone encoder “T,” pocket beep (tone squelch)
“
S
T SQL,” tone squelch “T SQL,” DTCS beep “
S
DTCS,”
DTCS squelch “DTCS,” tone squelch reverse “T SQL-R,” DTCS
squelch reverse “DTCS-R” and no tone operation are select-
able in order.
• While continuing to push
[TONE]
(0), rotate
[DIAL]
also selects
a tone setting.
e
Operate the transceiver in the normal way.
r
When the received signal includes a matching tone/code,
the squelch opens and the signal can be heard.
When the pocket beep function is activated, the trans-
ceiver also emits beep tones and blinks “
S
.
”
• When the received signal’s tone/code does not match, tone/
DTCS squelch does not open, however, the S-indicator shows
signal strength.
• To open the squelch manually, push and hold
[MONI]
(BAND).
t
Push
[PTT]
to answer or push and hold
[MONI]
(BAND)
for 1 sec. to stop the beeps and blinking.
