Getting Started
The radio will return to the settings in effect when it was last powered off, the LCD
will show the corresponding information and all controls will be operative. The radio
will then be in Standby mode.
Volume
The On-Off Power/Volume knob on the transceiver and the Volume Up/Down
buttons on the microphone/speaker control 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 you can
choose one of the following:
a. Turn the On-Off Power/Volume knob clockwise.
b. Press and release the Volume Up button on the
microphone/speaker.
To decrease the volume you can
choose one of the following:
a. Turn the On-Off Power/Volume knob anticlockwise.
b. Press and release the Volume Down button on the
microphone/speaker.
When adjusting the volume while using the microphone/
speaker, press and hold the Volume Up or Volume Down
buttons for rapid advance.
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 anticlockwise,
turn the On-Off/Volume knob clockwise until you
hear a hissing (noise) sound.
NOTE
Although the Volume Up/Down buttons on the
microphone/speaker can be used in the squelch
process, the On-Off Power/Volume knob is
recommended to control volume for optimum tuning.
