5. Check if the DMX cables run near or run alongside to high voltage cables that may cause
damage or interference to DMX interface circuit.
C. One of the channels is not working well
1. The stepper motor might be damaged or the cable connected to the PCB is broken.
2. The motor’s drive IC on the PCB might be out of condition.
7. Fixture Cleaning
The cleaning of internal and external optical lenses and/or mirrors must be carried out periodically
to optimize light output. Cleaning frequency depends on the environment in which the fixture
operates: damp, smoky or particularly dirty surrounding can cause greater accumulation of dirt on
the unit’s optics.

Clean with soft cloth using normal glass cleaning fluid.

Always dry the parts carefully.

Clean the external optics at least every 30 days.
