Squelch
The squelch control on the rear of the receiver is preset well at the
factory, if you must use the system in an area with considerable RF
interference and there is some noises from the receiver when your
transmitter is off, you can adjust the squelch control, so the system
will receive the signal from your transmitter only but squelch or
eliminate the unwanted background RF noise.
This adjustment can cause reduction in useable range of the wireless
transmitter, so set the control to the lowest position that reliablly mutes
the unwanted RF signals.
