Shape
- DMX LED should be on. If not, check DMX connectors, and cables to see if link properly.
- If the DMX LED is on and no response to the channel, check the address settings and DMX polarity.

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 surroundings can cause a 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 20 days. Clean the internal optics at least every 30/60 days.
