Solution
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,
reduce the distance between transmitter and
receiver.
Turn up the receiver audio output LEVEL
control.
Check for proper connection between
receiver 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.
Check Power/Battery Fuel Gauge and
replace 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
antennas. If possible, move them closer to
the transmitter.
Adjust receiver squelch control.
Adjust receiver squelch control.
Remove local sources of RF interference,
such as lighting equipment.
Reposition the receiver or antennas.
Reposition receiver and perform another
"walkthrough" test and observe the RF level
or Diversity signal indicators. If audio
dropouts persist, mark these "dead spots" in
the performing area and avoid them during
the performance.
