Solution
Slide the POWER ON/OFF switch on the transmitter
to ON. Make sure that the batteries are properly
inserted with the correct polarity (+/-). If the
batteries are correctly inserted, replace them by new
ones.
Check if the mains adaptor is plugged correctly into
the mains outlet and the DC socket. Make sure that
the mains outlet supplies the proper voltage
Increase the volume on the receiver. Check the
output connections from the receiver to the external
equipment
Make sure that the frequencies of the receiver and
the transmitter match.
Move the transmitter closer to the receiver
Replace transmitter battery
Identify potential sources of interference (other RF
sources) and turn off, remove or use a wireless
system operating on a different frequency
Reposition receiver and perform walk-through test
again. If audio dropouts persist, mark "dead" spots
and avid them during performance
