The squelch enables the audio to be heard only while 

receiving a signal that is stronger than the set level. A higher 

level blocks weak signals, so that you can receive only 

stronger signals. A lower level enables you to hear weak 

signals.

1.   Push [SQL] to enter the 

Squelch Adjustment 

mode.

2.   Rotate [DIAL] to adjust the squelch level, until the noise 

just disappears.

3.  Push [16/C] to exit the Squelch Adjustment mode.

■

The VOX function automatically switches between receive 

and transmit by detecting your voice.
