Wireless Tips to Improve System Performance
If you encounter wireless interference or dropouts, try the following suggestions:
• Replace the transmitter batteries
• Choose a different frequency channel
• Reposition the antennas so there is nothing
obstructing a line of sight to the transmitter (in-
cluding 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
• Remove nearby sources of wireless interfer-
ence, such as cell phones, two-way radios,
computers, media players, and digital signal
processors

Solution
• Check the power supply of the microphone and receiver.
• Ensure that the batteries are inserted correctly.
• Set the transmitter and receiver to the same channel.
• Check that the receiver is connected to the input on the audio mixer or
amplifier.
• Check that the transmitter is not too far away from the receiver.
• Decrease (counterclockwise) the squelch.
• Set the bodypack audio input switch to MIC.
• Make sure that the receiver has a clear, line-of-sight path to the transmitter.
• Keep the receiver away from metal objects.
• Replace the transmitter batteries.
• Check the receiver antenna location. Make sure there is a clear path between
the receiver and the transmitter.
• When using two or more systems simultaneously, chose different channels
within the same group (channels 1-4 or channels A-D).
• Turn off or relocate possible sources of interference such as cell phones, ra-
dios, or other electronic devices.
• Increase squelch (clockwise) to restrict the receiver from picking up ambient
noise.
• Unplug any unused receivers
• Adjust levels on the mixer board or sound system.
• Make sure all cables are securely connected from the receiver to the sound
system.
• If using a bodypack transmitter, lower the gain settings.
• Keep transmitters more than two meters (6
feet) apart
• Keep the transmitter and receiver more than 5
meters (16 feet) apart
• Keep them away from large metal objects
• During sound check, mark trouble spots and
ask presenters or performers to avoid those
areas
