Adjusting the Squelch
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.
1 Press [F], [MONI/SQL].
• The current squelch level appears.
2 Turn the Tuning control 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)
3 Press any key other than [LAMP], [MONI/SQL] to
store the new setting and exit the squelch
adjustment.
