Troubleshooting
Problems
No sound output, RF/AF LED(s) are not glowing
Received signal is noisy or contains extraneous
sounds with the microphone(s) ON.
There is noise coming from the receiver with the
microphones turned OFF.
Momentary loss of sound as microphone(s) are
moved throughout the operating range.
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 neces-
sary.
• Check receiver’s AC power connection.
• Make sure antennas are firmly connected and ex-
tended to an optimal position.
• If necessary, reduce the distance between the mi-
crophones 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 else-
where in the sound system.
• Check microphone(s) batteries and replace if the
charge is low.
• Remove local sources of UHF interference, such as
lighting equipment.
• Adjust the squelch controls on the front of the UHF-
8800 receiver.
• 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.
