SAFETY GUIDELINES
The following safety guidelines should be followed at all times. Failure to do so could seriously damage the
projector unit, or create a hazard to the service personnel or projector unit owner, and may violate warranties
on the product.
This product operates on mains voltage. Make sure to unplug the power cord before
attempting to open the unit. To avoid burns, do not open the unit to replace parts until it has
cooled down completely after use. The interior of the projector becomes hot during operation.
Do not under any circumstances operate the lamp whilst the housing is open, as there is a risk
of permanent injury due to contact with high voltage elements, explosion of the glass lamp
bulb or exposure to high levels of UV radiation.
The UHP-lamp used is high voltage when starting and high-pressure when operating.
