Problem
Solution
No sound; receiver RF light(s) and
AUDIO lights not glowing.
Make sure POWER switches on transmitter
and receiver are on.
Check transmitter Power/Battery Fuel
Gauge to ensure that battery is providing
power. Replace battery if necessary.
Check receiver squelch setting.
Check receiver antenna connection(s).
Make sure at least one antenna is in the line
of sight of the transmitter. If necessary, re-
duce the distance between transmitter and
receiver.
No receiver sound; RF and Audio Level me-
ter lights glowing.
Turn up the receiver audio output LEVEL con-
trol.
Check for proper connection between re-
ceiver and microphone mixer.
Talk into the microphone and observe the
receiver audio level lights. If they glow, the
problem is elsewhere in the sound system.
Received signal is noisy or contains
extraneous sounds with transmitter on.
Check Power/Battery Fuel Gauge and re-
place battery if power is low.
Remove local sources of RF interference,
such as lighting equipment .
If using a guitar or other instrument, make
sure it is connected to the LX1 with a Shure
WA302 adapter cable.
Two transmitters may be operating on the
same frequency. Locate and turn one off.
Signal may be too weak. Reposition anten-
nas. If possible, move them closer to the
transmitter.
Adjust receiver squelch control.
Noise from receiver with transmitter off.
Adjust receiver squelch control.
Remove local sources of RF interference,
such as lighting equipment.
Reposition the receiver or antennas.
Momentary loss of sound as transmitter is
moved around performing area.
Reposition receiver and perform another
“walkthrough” test and observe the RF level
or Diversity signal indicators. If audio drop-
outs persist, mark these “dead spots” in the
performing area and avoid them during the
performance.
