local authorities or your dealer about the way to proceed.
Signal indicators A/B are on
Signal indicators A/B on the
receiver are off when the sound
is lost
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
