Uniden Uh088sx Cb Tranciever Owners Manual

2. Think of the Squelch control as a gate. If you turn SQUELCH
fully clockwise it raises the Squelch Gate so
that no signals get through.
3. If you turn the SQUELCH fully counter clockwise, it lowers the
Squelch Gate so that everything gets through - noise,
weak signals and strong signals.
4. To set the Squelch Gate to the desired level, turn SQUELCH
counterclockwise until you hear noise. Then turn the SQUELCH
clockwise just until the noise stops. Now only strong signals get through.
