3. Squelch Adjustment
In normal operation, the SQUELCH CONTROL (6) should be set fully clockwise to the factory
preset RF level (Max. Sens.). However, in areas of high RF activity, the squelch (or mute, as it is
sometimes called) may need to be adjusted to compensate for the adverse conditions in a
particular location. If, with the transmitter off, the receiver’s A and/or B DIVERSITY LED
INDICTORS (3) flicker or stay on, the squelch control should be turned counterclockwise until the
A and/or B LEDs extinguish.
When the squelch is properly adjusted, the A and/or B LEDs will only light when the system
transmitter is turned on. Turning the squelch control too far counterclockwise will reduce the
range, but yield a quieter squelch (mute) function. During operation, especially at ranges greater
than 75 feet, one or the other of the A or B LEDs may extinguish briefly. This is normal – the
unit’s Diversity reception ensures that the received audio will not be interrupted. When both
LEDs extinguish, the transmitter is out of range for that given location, and the user should m ov e
closer to the receiver to re-establish the radio link.
