No sound output, RF/AF
LED(s) not glowing.
• 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.
Received signal is noisy or
contains extraneous
sounds with the
microphone(s) ON.
• 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).
Noise coming from the
receiver with the
microphones turned OFF.
• Remove local sources of UHF interference, such
as lighting equipment.
• Reposition the receiver or antennas.
Momentary loss of sound as
microphone(s) are moved
throughout the operating
range.
• 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.
