inserted with the correct polarity (+/-). If the
batteries are correctly inserted, replace them by new
ones.
No sound
The red POWER indicator on the
receiver is OFF
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
No sound
The signal indicators A/B on the
receiver are glowing
Increase the volume on the receiver. Check the
output connections from the receiver to the external
equipment
No sound
The signal indicators A/B on the
receiver are off. The POWER
indicators on the transmitter and
receiver are glowing
Make sure that the frequencies of the receiver and
the transmitter match.
Move the transmitter closer to the receiver
Distortion level increases
gradually
The signal indicators A/B on the
receiver and LOW BATTERY
indicator on the transmitter are
glowing
Replace transmitter battery
Bursts of noise or other
audible radio signals are
present
Signal indicators A/B are on
Identify potential sources of interference (other RF
sources) and turn off, remove or use a wireless
system operating on a different frequency
Momentary loss of sound
as transmitter is moved
around the performing
area
Signal indicators A/B on the
receiver are off when the sound
is lost
Reposition receiver and perform walk-through test
again. If audio dropouts persist, mark “dead” spots
and avid them during performance
