Precautions on the Lamp
This projector uses a high-pressure mercury lamp, which must be handled 
carefully and correctly as described below.
The mercury lamp has the following characteristics.
•The lamp will gradually become darker over time.
•Impact, abrasion, or use of worn-out lamps may cause lamps to rupture 
(accompanied by a loud noise) or burn out.
•Lamps are more likely to rupture after the lamp replacement message is 
displayed (see “Replacing the Lamp” (P201)). Replace the lamp with a new 
one as soon as possible.
•Useful life of lamps varies widely from lamp to lamp and depending on the 
environment of use. Some lamps may fail or rupture soon after they are first 
used.
•Be prepared by keeping a spare lamp.

hour.
•Ruptured lamps may scatter shards of glass inside the projector. Contact the 
Canon Customer Support Center for cleaning and inspection of the projector 
interior and lamp replacement.
Precautions when replacing lamps that stop working
•If illumination suddenly stops, either when you turn the projector on or after it 
has been on for a while, the lamp may have ruptured. In this case, never 
attempt to replace the lamp by yourself. Always request service from the 
Canon Customer Support Center. 
•With ceiling-mounted projectors, the lamp may fall out when you open the 
lamp cover, or during replacement. During replacement, stand to the side of 
the lamp cover, not directly under it. 
•If the lamp ruptures, dust and gas (containing mercury vapor) may come out 
of the exhaust vents. If this happens, immediately open the windows and 
doors to provide ventilation to the room.
•If you accidentally inhale gas from the lamp or get any pieces in your eyes or 
mouth, consult a doctor immediately.
