No power. Check the connection cable of the power
unit and any extension-cables.
No sound; receiver RF-
indicator does not flash. Make sure POWER switches on transmitter
and receiver are on.
Check transmitter Power-LED to ensure that
Battery is providing power. Replace battery if
necessary.
Make sure that the receiver is in the line of
sight of the transmitter. If necessary, reduce the
distance between transmitter and receiver.
No receiver sound;
receiver RF-indicator
flashes. Turn up the receiver audio output LEVEL control.
Check for proper connection between receiver
and microphone mixer.
Talk into the microphone and observe the receiver
RF-indicator. If it flashes, the problem is elsewhere in
the sound system.
Received signal is noisy
or contains extraneous
sounds with transmitter
on. Check transmitter Power-LED to ensure that battery
is providing power.
Remove local sources of RF interference, such as
lighting equipment.
Two transmitters may be operating on the same
frequency. Locate and turn one off.

receiver closer to the transmitter.
Noise from receiver with
transmitter off. Remove local sources of RF interference,
such as lighting equipment.
Reposition the receiver.
Momentary loss of sound
as transmitter is moved
around performing area. Reposition receiver and perform another test and
observe the RF-indicator. If audio drop-outs persist,
mark these dead spots in the performing area and
avoid them during the performance.
