TONE SQUELCH OPERATION
■ Tone squelch operation
The tone squelch opens only when receiving a signal con-
taining a matching CTCSS (subaudible) tone.You can silently
wait for calls from group members using the same tone.
q Set the desired channel.
w Set the desired CTCSS tone in set mode.
•See p.7 for tone frequencies and programming information.
e Push [–] for 2 sec. several times until “TSQL” appears.
r When the received signal includes a matching tone,
squelch opens and the signal can be heard.
•When the received signal’s tone does not match, tone squelch
does not open, however, the S-indicator shows signal strength.
•To open the squelch manually, push [–].
t Operate the transceiver in the normal way.
y To cancel the tone squelch, push [–] for 2 sec. twice.
NOTE:The transceiver has 51 tone frequencies and con-
sequently their spacing is narrow compared with units hav-
ing 38 tones. Therefore, some tone frequencies may
receive interference from adjacent tone frequencies.
Tone frequencies and tone squelch ON/OFF settings are
automatically stored in memory channels for easy recall.
■ Pocket beep operation
This function uses CTCSS (subaudible) tones for calling and
can be used as a “common pager” to inform you that some-
one has called while you were away from the transceiver.
DWaiting for a call from a specific station
q Set the operating channel.
w Set the desired CTCSS tone in set mode.
•See p.7 for tone frequencies and programming information.
e Push [–] for 2 sec. several times until “ TSQLë” appears
in the function display.
r When a signal with the correct tone is received, the
transceiver emits beep tones and flashes “ TSQLë.”
t Push [PTT] to answer or push [–] to stop the beeps and
flashing.
•Tone squelch is automatically selected.
DCalling a waiting station using pocket beep
A subaudible tone matched with the station’s tone frequency
is necessary. Use the tone squelch at left or a CTCSS (sub-
audible) tone encoder (p. 7).
