Troubleshooting, cont.
No Sound Output, RF/AF LED(s) are 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.
• Make sure everything is connected firmly and properly
• Make sure there are no defective cables
• Make sure all of your components are turned on
• Make sure all of the components (amp, mixer, TV, etc.) are set to the proper inputs
There is 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.
