Squelch - Uniden UH825 Series Owner's Manual

Operation

Squelch

The squelch is used to eliminate the annoying background noise when
there is no signal present on a channel. The squelch circuit does this by
controlling when the radio's speaker turns on, based on the strength of
received signals.
Make sure to first select a channel not in use before setting
the squelch in your UH825 UHF-CB radio.
