If some of the receivers work but others don’t, check for bad batteries or earphones on the
receivers that aren’t working.
þ
If none of the receivers work, check to see if the power and baseband cable are connected to the
emitter and that the TX9 Power and Baseband Present Indicator lights are ON.
þ
Check to see if the modulator is connected properly to the sound system. The Frequency
Indicator should be lit and there should be activity on the MOD 232 Level Indicators.
þ
Make sure the “eye” is not covered up on the receiver. There must be clear line of sight between
the receiver eye and the emitter panel.

Make sure each channel is set to a different frequency on the MOD 232 modulator. Listen to the
audio signal through the Phones jack of the MOD 232 modulator. You can also hold a receiver in
front of the Infrared Test LED on the front of the MOD 232 modulator and listen to the audio
signal. If the signal is weak and noisy here, check the Input Level switch and Input Level
Control settings. Increase the input signal level from the sound system by turning up the mixer
control. If the signal sounds okay, you may need to re-position the emitter panels or add
additional panels.
NOTE: Make sure the powerline voltage does not fall below 94V, or system performance will be
greatly reduced!
