3.Squelch adjust is set too low. In areas of severe interference (large downtown urban areas, airports, military bases, etc) it may be necessary to turn the squelch up slightly to avoid outside interference.
4.Transmitter is out of range of receiver. The transmitters do have a maximum range of about
5.Batteries are very weak. Just before the batteries are about to die, the overall performance of the system can degrade dramatically. Make sure to check the battery status of both the transmitter and DELTA X system.
