Open the battery compartment using a coin in the slot in the bottom of the transmitter.
Remove the batteries.
2.
Lift the flap up and to your left. The back of the transmitter case will open like a
book, exposing the circuit board.
3.
Use the diagram in Figure 10 to locate the channel selector switches.
4.
Use the tip of a paper clip or a small screwdriver (not a pencil point) to move the
switches to correspond with the switch positions on the programming chart in Figure 10.
You must choose one of the standard R800 channels (A/C/E/G/I/J) unless there is
interference on each (extremely unlikely). Do not touch any other adjustments.
5.
Reinstall the batteries, then close the back of the Transmitter.
6.
Plug the microphone in and turn the transmitter on to provide a tuning signal for the
receivers.
7.
Change the R800 to the corresponding channel. (See Figure 10.)
