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 Set the operating frequency.

• Set the AF and squelch to the desired level as the normal opera-

tion.

w Set the desired subaudible tone in 

SET MODE

.

• See page 32 for programming.

e Push 

, then push 

.

• Repeat several times until “ ” appears when selecting CTCSS,

or “ ” appears when selecting DTCS.

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 and hold 

.

t Operate the transceiver in the normal way.
y To cancel the tone squelch, push 

and 

.

• Repeat several times until “ ” or “ ” disappears.

The transceiver has 50 tone frequencies and con-

sequently their spacing is narrow compared to units having
38 tones. Therefore, some tone frequencies may receive
interference from adjacent tone frequencies.

To prevent interference from adjacent tone frequencies,
using the frequencies as in the following table, is recom-
mended.
