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.
