Uniden UBC785XLT - Manual (Page 22)

Basic Operation
Turn the Scanner On
Turn the VOL control clockwise out of the detent position. The scanner automatically starts
scanning. Since there are no frequencies programmed in your scanner initially, you may not
receive any signals. Once you set the squelch and program some frequencies, you will be
hearing conversations regularly.
Setting the Squelch
To set the squelch, you must be in the hold mode, and you should not be receiving a signal
on your scanner.
1. Press
▲/HOLD until you do not hear a signal.
2. Make sure that the VOL is set to a comfortable
listening level.
3. Think of the Squelch Control as a gate.
Turn the SQUELCH control fully counter-clockwise.
This raises the "Squelch Gate" so high that only very strong
signals can get through.
4. Turn SQUELCH clockwise until you hear a hiss. This lowers the
"Squelch Gate" so that everything gets through – noise, weak
signals, medium signals and strong signals.
5. Turn SQUELCH back counter-clockwise just until the hiss stops.
Now the "Squelch Gate" allows only clear signals through.
