Suitable laser protection glasses are required for any activities at the device.
A few common problems that may occur during operation are shown in the following. Here are some sugges-
tions for easy troubleshooting:
The device does not work, no light and the fan does not work
1. Check the power connection and main fuse.
No response to the DMX controller
1. If the word "signal" flashes in the display, no DMX signal is being received. Check the DMX connectors and
cables to see if they are properly linked.
2. If the word "signal" does not flash in the display and there is no response, check the address settings and
DMX polarity.
3. Try to use another DMX controller.
4. Check if the DMX cables run near or alongside high-voltage cables that may cause damage or interference
to the DMX interface circuit.
If the procedures recommended above do not succeed, please contact our Service Center. You can find the

Cleaning
DANGER
Laser radiation!
During cleaning follow the instructions specified in section "Laser safety" on page 4.
DANGER
Laser radiation!
To avoid unintended laser emission, remove the safety key before you start to clean the
device.
Clean the optical lenses which are accessible from the outside periodically to optimise light output. The clean-
ing frequency depends on the environment in which the device 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 20 days.
