Note that switching the microphone on and off can cause interference
that will be heard if the microphone volume level of the amplifier system
is still set high.
Switching on wireless microphone receiver, power indicator will
illuminate to show it's under normal working. "RF-A" & "RF-B" will shine
to show signals are strong or not when microphone is working. Now this
wireless microphone system is ready to use, adjusting volume of amp-
lifier/receiver as requested. Please don't forget to switch off microphone
if wireless microphone system is not being used.
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 reliablely mutes the unwanted RF signals.
