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.  

Received 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.

Battery running low even after recharging.

SOLUTIONS

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.   .
 
Turn up the receiver's VOLUME level controls.

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.   

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).

Remove local sources of RF interference, such as 
lighting equipment.  

Reposition the receiver or antennae.

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

Replace rechargeable batteries (rechargeable 
batteries have a life of 500 hours of charging and 
recharging).
