Channels
This radio operates on any one of the marine band radio channels.

switched to the same channel and privacy code. To change the radio

mode.
Power High / Low
This feature permits selection of the transmit power level to High or
Low. The LCD indicator will display "HI" when it is in the high power
mode. Using low power, the radio will have a lower transmit range but
the battery life will be increased.
Pressing the PTT button, press the DOWN button to select the low
power. The LCD indicator, "HI" will disappear. To return to the high
power, press again the PTT button and UP button.
Squelch Level Adjustment
This function allows you to adjust the squelch level of your radio. To
change the squelch level, press the Squelch and Monitor button
briefly. The current squelch setting will appear. Use the UP or DOWN
button to change the setting. Press the PTT button or wait for 5
seconds to store your choice.
There are 8 squelch levels. Level 1 is the most sensitive (open) and
level 8 is the least sensitive (closed). Auto(Ao) is the optimum factory
setting and 'Off' is fully open, with constant static noise.
Monitor
The Monitor function is used to briefly check for activity on the current
channel, regardless of privacy code settings. It is the same as setting
the squelch level to 'Off'.
