NOTICE!
Possible data transmission errors
For error-free operation make use of dedicated DMX cables and do not
use ordinary microphone cables.
Never connect the DMX input or output to audio devices such as mixers
or amplifiers.
In the following we list a few common problems that may occur during operation.
We give you some suggestions for easy troubleshooting:
Symptom Remedy
The unit does not work, no light 1. Check the mains connection and the main fuse.
2. Check the safety key switch.
3. Check the external safety switch (e.g., emergency stop button).
No response to the DMX controller 1. If the display shows a flashing number, for example ‘001’, no DMX signal is
being received. Check the DMX connectors and cables for proper connection.
2. Check whether the DMX cables run near or parallel to high-voltage cables
that may cause damage or interference to a DMX interface circuit.
3. Try using another DMX controller.
No response to the remote control 1. Try using the remote control at a different angle to the IR sensor on the
front panel of the device.
2. Check the remote control battery.
If the procedures recommended above do not succeed, please contact our Service
Center. You can find the contact information at www.thomann.de .
