3.3 Operating Procedures
3.3.1 Turning the Power On
Rotate the VOLUME/PWR knob clockwise to turn the radio on.
3.3.2 Setting the Squelch
Rotate the SQUELCH knob counterclockwise until audio is heard. Rotate
clockwise until the squelch "quiets".
3.3.3 Setting the Volume
With audio present, rotate the VOLUME knob clockwise for the desired
volume level.
3.3.4 Setting the Power Output
Press the MON/1/25 key for two seconds to toggle between 1 watt output
and 25 watts output. When the 1W indicator is displayed, the output power
is 1 watt. If 1W is extinguished, 25 watts is being output.
The choice of power output is dependent upon the distance of transmission
and transmitting conditions. In certain US harbors and on certain channels,
the FCC requires the power to be limited to 1 Watt. On these "required"
channels, the radio automatically selects 1 watt power output when the
channel is selected.
3.3.5 Setting the Channel
To select the appropriate channel, rotate the CH (Channel Select) Knob
clockwise/counterclockwise or use the Channel UP/DOWN keys on the
microphone.
