No sound; receiver RF light(s) and mic(s) not lit.	Make sure POWER switches on transmitters and
	receiver are set to ON positions.
.	Check microphone batteries to ensure they are
	providing power.
	Replace or charge batteries if necessary.
	Check receiver's AC power connection.
	Make sure antennas are in the microphones' line of
	sight.
	If necessary, reduce the distance between the
	microphones and reciever. .

	Check for proper connection between receiver and
	external amplifier/mixer.
	Talk into the mic and observe the receiver's RF signal
	LEDs. If they glow, the problem is elsewhere in the
	sound system.
Received signal is noisy or contains interference with
transmitter on.	Check microphone batteries and charge or replace if
	power is low.
	Remove local sources of RF interference, such as
	lighting equipment. Two transmitters may be operating
	at the same frequencies or frequencies which are too
	close in proximity. Turn one off or exchange for one
	with a different frequency. Signal may be too weak. If
	so, reposition antenna (If possible, move them close to
	the transmitter).
