Troubleshooting
TX9 DC Indicator Light Is Not On.
• Make sure the power supply is plugged into the emitter.
• Make sure the electrical outlet is on.
• Make sure the power supply is working.
Only TX9 DC’s Power Indicator LED Comes On.
• Make sure the MOD 232 is on.
• Make sure the baseband cable is connected properly. See page 5, Figures 3 & 4.
• Check to see if the carrier light on the MOD 232 is on.
• Make sure an audio signal is being sent to the MOD 232.
No Sound Through Receivers.
• If some of the receivers work but others don’t, check for bad batteries or earphones on the receivers that aren’t working.
• If none of the receivers work, check to see if the power and baseband cable are connected to the emitter and that the TX9 DC
Power and Baseband Present Indicator lights are ON.
• 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.
• 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.
Sound Through The Receivers Is Weak And Noisy.
• 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.
Buzzing Or Humming Noise In Sound System.
• Check for ground loops or noise on the input signal. Call your Authorized Williams AV dealer or representative.
