2. ADJUSTING SQUELCH
Squelch is used to eliminate static and background noise between received
transmissions. Squelch effectively mutes the radio speaker until it receives a
transmission, thus sparing you from having to listen to static. If Squelch is set too high,
only the strongest transmissions can be heard, and if it is set too low, intermittent static
and noise may be annoying. Squelch is controlled by the SQUELCH knob located on the
radio base station.
T
o set Squelch:
1. Turn the SQUELCH knob counter-clockwise as far as it will go. You will hear a
lot of static.
2. Then turn the SQUELCH knob clockwise until the static stops; this is the correct
position for the SQUELCH knob.
3. Repeat steps 1 and 2 to re-adjust as necessary.
3. SELECTING A CHANNEL
Use the Up/Down key on the microphone handset or the CH/ENTER knob on the radio
base station to scroll through the available channels. See Marine Channels for a list of
channels and their frequencies.
T
o select a channel:
1. To select a channel, use the Up/Down key on the microphone handset or turn
the CH/ENTER knob on the radio base station back and forth to find a channel.

Memory or Normal mode. In Memory mode (MEM), you will only see the saved channels. See

Normal Channel mode, press and hold the HI/LO/MEM key for 3 seconds, or press and
