■ Tone squelch operation
D Operation
The tone squelch opens only when receiving a signal con-
taining a matching subaudible tone. You can silently wait for
calls from group members using the same tone.
q Assign the main band to the desired display with [MAIN].
w Set the operating frequency.
e Set the desired CTCSS tone in set mode.
•See right for programming.
r Push [TONE] several times until “TSQL” appears.
t 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 and hold [SQL].
y Operate the transceiver in the normal way.
u To cancel the tone squelch, push [TONE].
NOTE:The transceiver has 50 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.

Store subaudible tone frequencies and tone squelch ON/OFF
settings in memories (call) for easy recall.
D Setting subaudible tones for [
tone squelch operation (CTCSS tones)
Separate tone frequencies can be set for tone squelch oper-
ation than for repeater operation (the same range of tones is
available—see below). Like repeater tones, these are set in
set mode.
q Select VFO or a memory channel.
w Push [
(H/L)SET]for 2 sec. to enter
set mode.
e Push [
(H/L)(SET)J] or [(TONE)K]
several times until “CT” appears
as shown at right.
r Rotate [DIAL] to select the de-
sired subaudible tone.
t Push [
(VFO)CLR] to exit set mode.
