connect further »PRO IR-400« transmitters (Slaves), linked to the primary transmitter (Master).
The devices are linked by connecting the according Sync-Out-ports of the first transmitter to
the Sync-In-ports of the next transmitter, as illustrated in the following figure G):

Troubleshooting
Should you have problems with your infrared system, please check the following points before
requesting service.
No infrared emission:
- Make sure the power adaptor is connected to a Mains outlet.
- Make sure that the Mains outlet is supplied with electricity (check external switches etc.)
Input indicator LED does not light up:
- Make sure the »PRO IR-400« is plugged in properly
- Check if the Audio-In is connected to the Audio-Out of the source.
- Verify that a sufficient audio signal is sent to the »PRO IR-400«.
No sound produced by the receivers:
- Make sure the receivers are set to the frequency of the transmitter.
- Should some receivers work but others not, it is adviseable to check the batteries of the
receivers.
- If no receiver is working, please check if the input indicator LEDs are on.
- Check to see if the transmitter is connected properly to the audio source. The audio-level
indicators should flash on channels that have audio.
- Make certain the transmitter is not covered by objects which would block infrared light.
Sound reproduction of receivers is low and interferred:
- Try to adjust the Audio-In level. Should the sound be in order, then it may be necessary to
reposition the transmitter or add a further »PRO IR-400« to the system.
Poor sound quality, distorsions:
- Check for ground loops or noise on the input signal.
- Check the input signal for overload.
- Distance between transmitters and receivers is out of optimum.
Interruptions in transmission:
- Distance between transmitters and receivers is out of optimum.
- Inappropriate position of transmitter (Consider relocating the transmitter or receivers, avoid
obstructions in the line of sight between transmitter and receivers).
If these instructions do not address your problem or the issue persists, please call
Humantechnik or your authorized dealer or representative.
