Always it's good idea to keep "open space" between transmitter and receiver, which is able to
improve RF reception.

body-pack transmitter. Both receiver and transmitter are pre-programmed with 16 channels (Figure

Then, with the UP/DOWN button, select the channel of receiver the same as the transmitter,
please make sure the receiver channel matches that of the transmitter.
When two or more transmitters and receivers 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 non-
interference channel.
