Adjusting the Squelch Level

The purpose of Squelch is to mute the speaker when no signals are present. With the squelch level correctly set, you will hear sound only while actually receiving signals. The higher the selected squelch level, the stronger the signals must be to receive. The appropriate squelch level depends on the ambient RF noise conditions.

1Press [F], [MON].

•The current squelch level appears.

2Rotate the Selector (or press [UP]/ [DOWN]) to adjust the level.

•Select the level at which the background noise is just eliminated when no signal is present.

•The higher the level, the stronger the signals must be to receive.

•6 different levels can be set. 0: Minimum ~ 5: Maximum; 2 is the default value.

3Press any key other than [MON], [UP]/ [DOWN] or [] to store the new setting and exit the squelch adjustment.
