TIPS TO OBTAIN THE BEST RESULTS 1. Position the receiver so that it has the fewest possible obstruction between it and the normal location of the transmitter. The transmitter and receiver should be as close together as conveniently possible. The receiver antenna should be in the open and away from any metal or cement walls. If in a rack, have the unit on top or angle antennas outward away from the metal rack. A receiver cannot receive signals from two transmitters at the same time. 6. Each transmitter/receiver system operates on a factory-aligned, crystal co trolled frequency. This number must match the transmitter if you purchase a replacement transmitter. 7. Remove the battery if the transmitter is not used for a period of time. TRANSMITTER B2 B3 HEAD MIC A1 Fig. C Front View BELT-PACK TRANSMITTER BATTERY INSTALLATION An alkaline 9-volt battery is recommended. Carefully insert a fresh 9-volt alkaline battery, observing correct polarity as marked inside the battery compartment. The transmitter housing is designed to prevent incorrect installation of the battery. [. . . ] Please note that wireless frequencies are shared with other audio services.
