6. System Operation
Be sure to mute the audio signal of a mixer or amplifier before turning on the receiver and
transmitter.
(1) Power on
Turn AF level on the receiver completely counter-clockwise to the minimum level, and switch
on the receiver. As soon as you turn power of the receiver on, the power LED lights
red, meanwhile the RF signal and AF LED light up to indicate the system is ready for
operating.
It is always a good idea to keep “open space” between transmitter and receiver, that will improve
RF reception.
(2) Selecting channel for the receiver and transmitter
1. Use the supplied screwdriver to select a desired channel for the receiver and transmitters .
Both receiver and transmitters are preprogrammed with 16 channels.
2. Make sure the channel of receiver matches that of the transmitter.
3. When 2 or more system are being used in the same location, they must be set up to use
different channels. If existing channel is being interfered, please change to another
non-interference channel.
