Safety Precautions
Lamp
This projector uses a high-pressure mercury lamp. 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 “Lamp replacement” (
)). 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.
Note the following precautions during lamp replacement or when a lamp has
ruptured.
Note the following precautions when replacing lamps that stop working. Failure to
do so could result in personal injury.
• 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. Ruptured lamps may scatter shards of
glass inside the projector. Contact a qualified technician
or the Canon Customer Support Center for cleaning and
inspection of the projector interior and lamp replacement.
• If you accidentally inhale gas from the lamp or get any pieces
in your eyes or mouth, consult a doctor immediately.
• 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 a qualified
technician or 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, make sure no one is under the projector, and
stand to the side of the lamp cover, not directly under it.
