Troubleshooting
No sound output
• Make sure the microphone and receiver power switches are set to the ON position.
• Check microphone batteries to ensure that they are providing sufficient power. Let battery charge or replace 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 signal LED’s on the display screen. If they glow, the problem
is elsewhere in the sound system.
• Make sure the mic and its corresponding receiver channel are set to the same frequency.
Received signal is noisy or contains extraneous sounds with the microphone(s) ON
• Check microphone(s) batteries and recharge or replace if the 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.
• Try increasing the “Squelch” in the receiver
• Try setting the RF Power Level to HIGH. he RF Power Level switch is located inside the battery compartment of
each microphone. See the instuctions for “Setting the RF Power Level” in this manual.
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.
Battery running low even after recharging
• Replace rechargeable batteries (rechargeable batteries have a life of 500 hours of charging and recharging).
The Mic is switched on and the mic’s display screen is on but there is no sound
• Make sure the mic and its corresponding receiver channel are set to the same frequency.
• Make sure the volume on the receiver is turned up.
The microphone is switched on but its display screen is not on
• Replace or recharge the mic’s batteries
The vocals become weaker as I walk further away from the receiver
• Switch the RF Power Level to HIGH. The RF Power Level switch is located inside the battery compartment of each
microphone. See the instuctions for “Setting the RF Power Level” in this manual.
