TROUBLESHOOTING

PROBLEMS

No sound: Receiver RF light (s)
and Mic (s) not lit

No Receiver sound but the RF
and Audio Level meter lights are
glowing

Receiver signal is noisy or contains
Interference with transmitter on.

Noise coming from the Receiver
with the Mics turned OFF

Momentary loss of sound as
Transmitter Is moved around
performing area.

SOLUTIONS

Make sure POWER switches on transmitters
and receiver are set to ON positions .
Check microphone batteries to ensure they are
providing power. Replace battery if necessary.
Check receiver's AC power connection. Make
sure antennas are In the microphones's line
of sight. If necessary, reduce the distance
between the microphones and receiver

Turn up the Receiver's VOLUME level controls.
Check for proper connection between receiver
and external amplifier /mixer.
Talk into the Microphone and observe the
Receiver's RF signal LEDs, If they glow, the
problem is elsewhere in the sound system

Check Microphone batteries or replace if power
is low. Remove local sources of RF interference,
such as lighting equipments, 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
antenna.
(If possible, move them close to the transmitter)

Remove local sources of RF interference,
such as Lighting equipment.
Reposition the Receiver or Antennas.

Reposition receiver and perform a "walkthrough"
test and observe the signal strengths, If audio
dropouts persist, mark these "dead spots" in the
performing areas and avoid them during the
performance.
