is sent to the radio. You will hear the message through

whichever speakers are connected to the radio.

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.

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 

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.

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.

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.

To Receive Weaker Signals:

1. 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.
