General Hints
ATTENTION
U
Any work on electric supply wiring must be carried out by competent electricians.
U
Make sure that nobody starts projector while you are working on it. For all mainte-
nance, cleaning and repair you must disconnect the projector from its power supply
(switch off the main switch).
U
All adjustments must be carried out by experts.
Because of using many maintenance-free parts, the consumption of material and the
expenditure of time for maintenance work and repair are reduced to a minimum.
The necessary maintenance and cleaning work may be performed by the projector’s
operators. This work has to be carried out regularly and carefully. See the following lists
regarding the schedule for this work.
Do every week
• Check the operating hours of the xenon lamp and if necessary, change it.
• Clean lens. Use a linen cloth but wipe only in one direction.
• Clean the porthole.
• Check image settings.
• Clean projector on the top side with a vacuum cleaner.
