Adjusting The Squelch - Uniden BC350C Manual

3. Set the squelch at the scanning threshold by turning [SQ]
counterclockwise just until the noise disappears.
4. Press any of the Service bank keys: [POLICE],
[FIRE/EMS], [AIR], [WX], [CB], or [MRN]. The scanner
automatically starts scanning the selected bank.
Note: Later, when you have learned how to program chan-
nels in the PRIVATE bank, you can press [PRIVATE] to
scan your favorite collections.
5. Adjust the volume to a comfortable listening level.

Adjusting the Squelch

1. Open the squelch by turning [SQ] clockwise to the end.
You should hear a steady sound (scanning stops).
2. Turn [SQ] counterclockwise slowly until the sound disap-
pears. This is the threshold point at which scanning starts.
At the squelch threshold, an incoming signal just slightly
stronger than the noise will open the squelch.
Note: When squelch is open, you can hear the voice
(scanning is stopped). If squelch is set too tight, that is, too
far counterclockwise from the threshold point, a stronger
signal is required to open the squelch.
If squelch is set on a point clockwise from the threshold,
you will hear a constant sound (noise, if no signal is pres-
ent). The scanner will not scan.
