Solutions
Make sure that the transmitter and receiver are both
powered on.
Ensure the transmitter's batteries are installed correctly.
Check that the transmitter is not muted.
Confirm that the CR88x adapter is correctly connected
and plugged into an electrical outlet.
Turn on the CR88x receiver.
Make sure the CR88x audio output connections are
securely connected.
Ensure that the receiver and transmitter are in line of sight
with one another.
Check the receiver and audio input device level controls.
Ensure that the transmitter and receiver are set to the
same operating channel. If unsure, reset the channel by
following the steps in the "Quick Start".
The receiver output level or audio input device level may
be too high.
Check the transmitters batteries, and replace if low.
The input gain on the transmitter (CH88 or CB88) or audio
source level may be too high.
The transmitter may be too far away from the receiver.
Move it closer to the receiver, or reposition the antennas.
Remove any sources that may cause RF interference such
as cell phones, cordless phones, lighting equipment,
computers, metal structures, etc.
Check the adapter to ensure it is properly connected and
plugged into an outlet providing power.
Replace the transmitter batteries.
If using multiple systems, make sure none of the systems
are operating on the same channel. If the problem
persists, change one or all of the systems channels.
