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 cor-
rectly 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 equip-
ment
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
avoid them during performance
