Getting Started
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
anticlockwise.
Squelch
Squelch control filters weak signals and radio frequency noise so that you can hear
the signals you want more clearly. 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.
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 anticlockwise (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.
