4.To set the SQUELCH control to AUTO turn fully counterclockwise until control clicks into place. Or, manually set squelch as follows:
■Think of squelch as a gate. Turn SQUELCH fully counter clockwise. This raises the “Squelch Gate” so high that only very strong signals can get through.
■Turn SQUELCH fully clockwise until you hear a hiss. This lowers the “Squelch Gate” so that everything gets through — noise, weak signals, and strong signals.
■Turn SQUELCH back counter clockwise until the hiss stops. Now the “Squelch Gate” allows only strong signals through.
