Getting Started

Squelch Control

Squelch is controlled by turning the lower rotary concentric knob located directly below the On/Off/Volume switch.

With the power On, turn the knob counterclockwise until you hear a hissing sound, then turn the knob clockwise until 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 in a counterclockwise direction (further 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-Watchfunctions will be blocked.

Radio Speaker and Microphone

The internal Radio Speaker and Microphone are located on the bottom front face of the radio below the lower control buttons.

An optional Speaker/Microphone port is located at the top of the radio between the antenna and the Power/Volume/Squelch control. Unthread the Speaker/Microphone port cover to access and install an optional speaker or microphone into this port.
