Safety Instructions
Safety Instructions
Pay attention to the following points regarding installation and handling of the projector.
Failure to do so may cause a fire, electric shock or personal injury.
• Do not remove the cabinet from the projector or disassemble it. The interior
of the projector contains high-voltage components as well as parts that are
hot. If inspection, maintenance or repair is required, contact the Canon
Customer Support Center.
• Do not disassemble or modify the projector (including consumable parts) or
the remote control.
• Do not look directly into the exhaust vents during use.
• Do not insert any object into vents in the projector, such as the air intake vent
or exhaust vents.
• Do not place a pressurized can in front of the exhaust vents. The pressure of
the contents of the can may increase due to heat from the exhaust vents and
this could result in an explosion.
• When cleaning off dust or dirt from projector parts such as the lens or filter,
never use any spray that is flammable. Internal parts that become hot may
ignite and cause a fire.
• Light from the projector is classified as
Risk Group 3 (RG3) according to
IEC 62471:2006.
• Possibly hazardous optical radiation emitted
from this product. Do not look at operating lamp. Eye injury may result. Pay
particular attention to prevent small children from doing so.
• When setting the projector on a high surface for projection, be sure the
surface is flat and stable.
• Do not use the projector on a soft surface such as carpet or sponge mat, etc.
Doing so could cause heat to build up inside the projector and this could
result in a fire.
• For ceiling mounting precautions, refer to the installation manual included
with the ceiling mount (sold separately).
• When hanging the projector from a ceiling, put the projector down on the
floor or a workbench before attaching or replacing the lens unit. Failure to do
so could result in parts falling off the projector and may cause an accident or
personal injury.
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” (P173)). 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.
