Volume
The On-Off Power/Volume knob also 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, which is controlled by the
circuitry of your radio.
To increase the volume:
1. Turn the On-Off Power/Volume knob clockwise.
To decrease the volume:
1. Turn the On-Off Power/Volume knob anticlockwise.
Squelch
Squelch control filters weak signals and radio
frequency noise so that you can hear the signals
you want more clearly.
To squelch your radio:
1. With the Squelch knob turned fully anticlockwise,
turn the On-Off Power/Volume knob clockwise until
you hear a hissing (noise) sound.
2. Turn the Squelch knob clockwise until the hissing
sound stops. Turning the Squelch knob further clockwise
will filter weak and medium strength signals until only the
strongest signal can get through at its highest setting.
To receive weaker signals, turn the Squelch knob
anticlockwise.
If the squelch is set so you can hear a continuous hissing
sound, the scan and dual-watch functions will be blocked.
