LAMP REPLACEMENT
The projector uses a high-pressure mercury glass lamp which can explode with a loud
bang, or burn out, if jolted or scratched or handled while hot, or wear out over time. If the lamp should
explode, immediately disconnect all power sources to the projector. Ventilate the room well, and make sure
not to breathe the gas that comes out of the projector vents. Avoid contact with eyes and mouth.
Do not use an old (used) lamp as this may cause it to explode.
Do Not operate a projector while any lamp is removed. This may result in malfunctions, fire
hazard, or other accidents.

When replacing a lamp that has burnt out, wait at least 45 minutes for the lamp to cool
sufficiently. Handling the lamp while hot can cause burns, as well as damaging the lamp. Shards of glass
may damage internal projector components or cause injury during handling.
Never unscrew except the appointed (marked by an arrow) screws.
Do not open the lamp cover while the projector is suspended from above. This is
dangerous as the shards from the broken bulb will fall out when the cover is opened.

experiencing electrical problems other than the lamp itself. If this occurs, contact your local dealer or a

When the pictures appears dark, or when the color tone is poor, replace the lamp as soon as possible.
