Operating Your Radio

Squelch Knob

Channel Select Knob

Getting Started

Squelch

Squelch control is controlled by turning the inner (back) rotary concentric knob located directly behind the On/Off – Volume knob. With the power On, turn the knob counterclockwise till you hear a hissing sound, then turn the knob clockwise till the hissing stops. This will establish a “Baseline” squelch.

By turning the knob further in a clockwise direction, you will filter weak and medium-strength signals. By turning the knob further in a counterclockwise direction from your baseline setting, you will receive weaker signals.

Squelch control filters weak signals and radio frequency (RF) noise so that you will clearly hear the signals you want.

NOTE

If the Squelch is set so that you can hear a continuous hissing sound, the Memory Scan and Tri-Watch functions will be blocked.
