Operation Manual

48 Ray218E and Ray55E Marine VHF Radios
Setting the Power Output (HI/LO)
The choice of power output is dependent upon the distance of transmission and
transmitting conditions. As a part of marine communications courtesy, make
initial contact using low power. Switch to high power only when contact can not
be made on low power or in emergency situations. International regulations state
that you must use the minimum power possible for satisfactory communication.
If conditions require that you change transmission power for the currently-
selected channel, select the HI/LO POWER menu option under VHF OPS. Press the
HI/LO soft key to toggle the TX power from LOW (1 watt) to HIGH (25 watts). The
corresponding LO or HI indicator appears.
You can also press the
HI/LO–LOC/DIS key on the microphone to toggle TX power.
