Ray54E VHF Radio

Press and release the

HL/USER key on the main unit or microphone to toggle

the TX power from LOW (1 watt) to HIGH (25 watts). The corresponding

HI indicator appears on the LCD.

As a part of marine communications courtesy, initial contact should always
be attempted using low power. You should switch to high power only when
contact can not be made on low power in emergency situations.

Note: Some channels are limited by regulation to be low power only. If the
HILO operation request is denied, an error tone beeps.
