Wireless Tips to Improve System Performance
If you encounter wireless interference or drop-
outs, 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
• 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
Troubleshooting
Problem Solution
No sound
• 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.
Noise from RF
interference
• 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). For the JB1 band, there are three
groups: channels 1-3, 4-6, and 7-8.
• Turn off or relocate possible sources of interference such as cell phones, radios, or
other electronic devices.
• Increase squelch (clockwise) to restrict the receiver from picking up ambient noise.
• Unplug any unused receivers
Audio distortion
• 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.
