14 Ray101E Handheld VHF Radio
4.3 Setting the Squelch
The Squelch circuit sets the threshold for cutting
off the receiver when the signal is too weak for
reception of anything but noise.
To properly set the squelch, rotate the SQ knob
counter clockwise until noise is heard.
Then rotate clockwise until background noise
disappears.
4.4 Setting the Power Output
Press and release the HI/LO / USER key to toggle the TX power from LOW
(1 watt) to HIGH (5 watts). The corresponding LO or HI indicator appears on
the LCD.
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. This procedure is part of marine communications
courtesy and will save on battery life.
Note: Some channels are limited by regulation to be low power only. If the
HI/LO operation request is denied, an error tone beeps.
