program channel remains unchanged.
For normal operation, the transmitter displays the same channel as displayed on the receiver.

Note: The IR link is infrared light and thus works best when this data transfer is accomplished in a
light-shielded or darker environment. It may not be successful in a brightly lit area. If the transfer fails,
repeat the procedure in a darker location or somehow shield the link from outside light to successfully
program the transmitter with the pre-programmed group and channel info from the receiver.

COMPARTMENT DOOR (32) then swing down exposing the Battery Compartment (31). Insert
two fresh AA batteries according to the polarity indicated on the transmitter body. Secure the
battery cover back onto the microphone. Fresh alkaline batteries can provide up to 8-10 hours
