TROUBLESHOOTING
Turn on the receiver, but
the indicator is not lighted. Make sure if the power cable is well
fixed. Is the socket in a good condition?
Is the fuse blown?
When you speak toward
the microphone, the СНА
or CHB power indicator is
shining, but no sound
output.
Make sure if the volume keep in lowest
place, or the audio cable is not fixed
well.
The effective signal-
receiving distance become
close and signal receiving
is not well.
Perhaps you have not put out the
antennas or should change a new
battery. Perhaps the receiver is not put
in right place or there is a strong
magnetic field in your surroundings.
Timbre becomes bad. Perhaps the voltage of the battery is not
enough. You need change the battery.
Or perhaps there are the same
frequency signals in your surroundings.
Do not use two machines with the same
frequency at the same time in a place.
