Troubleshooting
No power:
Check battery and power supply connections and voltage.
Check the power switch on the transmitter.
The LCD displays “E0 00” or similar code:
Exit master list mode by
holding the SET button for ten seconds.
Can’t turn off or change settings on the transmitter or receiver:
The
interface is locked. See the section on locking the interface.
No audio:
If the antenna and battery indicators do not appear on the re-
ceiver, then it is not receiving a signal from the transmitter. 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 drop outs, 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.
