Can't turn off or change settings on the transmitter or receiver:
The interface is locked. See the section on locking the in-
terface.
No audio:
If the antenna and battery indicators do not appear on the receiver, then it is not receiving a signal from the transmit-
ter. Make sure the transmitter and receiver are tuned to the same group and channel.
Faint or distorted audio:
Adjust transmitter gain, bodypack attenuator switch, and receiver output level.
Noise:
Noise usually results from wireless interference or a weak signal from the transmitter. See Tips for Improving System
Performance.
Tips for Improving System Performance
If you encounter wireless interference or dropouts, try the following:
Replace the transmitter battery with a fresh alkaline battery (avoid rechargeable batteries).
Choose a different frequency channel.
Reposition the antennas so there is nothing obstructing a line of sight to the transmitter (including the audience).
Avoid placing transmitter and receiver where metal or other dense materials may be present.
Move the receiver to the top of the equipment rack (or remote mount antennas outside the rack).
Remove nearby sources of wireless interference, such as cell phones, two-way radios, computers, media players, and
digital signal processors.
Keep transmitters more then two meters (6 feet) apart.
Keep the transmitter and receiver more than 5 meters (15 ft) apart.
Point the receiver antenna tips away from each other at a 45° angle, and keep them away from large metal objects.
During sound check, mark "trouble spots" and ask presenters or performers to avoid those areas.
