MH-X25 LED Spot
Remedy
Check the mains power connection and the main fuse.
1. The DMX indicator should light up. If it doesn't, check
DMX connectors and cables for proper connection.
2. If the DMX indicator lights up but with no response,
check the address settings and DMX polarity.
3. Try using another DMX controller.
4. Check whether the DMX cables lie near or adjacent to
high voltage cables, which could cause damage or inter‐
ference with a DMX interface circuit.
