How Squelch Works
The squelch circuit in your scanner is like a
gate. If it is too low, everything gets through
... noise, weak signals, and strong signals.
If the gate is set too high, nothing gets
through ... not even the strong signals.
When the gate is correctly set, strong
signals get through, but weaker signals and
noise are blocked.

Setting the Squelch
Adjust VOLUME to a comfortable listening
level.
To set the Squelch, you must be in the
Manual Mode. No signal should be present
when adjusting Squelch.
1. Press (»mwi*!)until you do not hear a
signal.
