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 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.
• Do not use adhesives, lubricants, oils, or alkaline detergents for
maintenance of the projector. They could adhere to the cabinet and damage
it, possibly resulting in the projector falling from its mounting and causing an
accident or personal injury.
• As strong light beams are emitted while the
projector is in use, do not look directly into the
projector lens. Doing so could cause an eye
injury. Pay particular attention to prevent
small children from doing so.
• Light from the projector is classified as Risk Group 2 (RG2) according to
IEC 62471-5:2015.
• If children may approach the projector or touch it, always ensure the
projector is used under adult supervision.
• Do not hold or install optical instruments (such as magnifying glasses,
reflectors, or glasses) in the path of light from the projector. If projected light
is refracted or reflected and enters people’s eyes, it may result in eye injury.
• 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.
• Be sure to ask a qualified technician or the Canon Customer Support Center to
perform the installation work. Poor installation work could result in an accident.
• For ceiling mounting precautions, refer to the installation manual included
with the ceiling mount (Part No.: RS-CL16, sold separately).
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” (P174)). 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.
