HINTS FOR USING THE SYSTEM Normal operating distance between the transmitter and receiver is about 30 meters. The operating range will vary in different buildings and surroundings. In some locations, the signal may momentarily disappear. This is called a “drop-out” and is due to reflection and cancellation of the radio signal. Moving a few feet will restore the signal. Keep the transmitter and receiver units at least a meter apart. If the transmitter gets too close to a receiver, it can overload
