Solutions
Make sure the microphone and receiver power switches and
•
receiver are set to the ON position.
Check microphone batteries to ensure that they are providing
•
sufficient power. Replace battery if necessary.
Check receiver's AC power connection.
•
Make sure antennas are firmly connected and extended to an
•
optimal position.
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/AF signal
•
LED's. If they glow, the problem is elsewhere in the sound system.
Check microphone(s) batteries and replace if charge is low.
•
Remove local sources of UHF interference, such as
•
lighting equipment.
Signal may be too weak. If so, reposition antennas. (If possible,
•
move them closer to the transmitter).
Remove local sources of UHF interference, such
•
as lighting equipment.
Reposition the receiver or antennas.
•
Reposition the receiver, perform a "walkthrough", and observe the
•
signal strengths. If audio dropouts persist, mark these "dead
spots" in the operating area and avoid them
during the performance.
