Operating Your Radio Getting Started Volume The On-Off Power/Volume knob on the transceiver controls the speaker volume. The volume adjustment applies only to what you hear from the speaker and does not affect the volume of your outgoing messages. That is controlled by the circuitry of your radio. On-Off Power/ Volume Knob To Increase The Volume: Turn the On-Off Power/Volume knob clockwise. To Decrease The Volume: Turn the On-Off Power/Volume knob counter-clockwise. Squelch Squelch control filters weak signals and radio frequency noise so that you can more clearly hear the signals you want. You can think of it as a variable barrier that blocks what you don't want to hear. Squelch Knob To Squelch Your Radio: 1. With the Squelch knob turned fully counter-clockwise, turn the On-Off/Volume knob clockwise until you hear a hissing (noise) sound. Turn Until Hissing Sound Starts 2. Turn the Squelch knob clockwise until the hissing sound stops. Turning the Squelch knob further clockwise (higher bearier) will filter weak and medium strength signals until only the strongest signal can get through at the highest squelch setting. Turn Until Hissing Sound Stops Lower Bearier NOTE To receive Weaker Signals Turn the Squelch Knob counterclockwise (lower bearier). If the squelch is set so that you can hear a continuous hissing sound, the scan and dual-watch functions will be blocked.
