Precautions on the lamp

This projector uses a high-pressure mercury lamp as a light source. 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 once the lamp replacement message has been displayed. Replace the

lamp with a new one as soon as possible. For details, refer to the user’s manual.

• 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.

Take the following precautions during lamp replacement or when a lamp has

ruptured. Failure to do so may result in electric shock, burns, or other injury.

• Before replacing the lamp, always unplug the projector and wait at least 45 minutes.

• Ruptured lamps may emit dust and gas (containing mercury vapor) out of the exhaust vents. If so,

immediately open windows and doors to ventilate the room. Additionally, shards of glass may be

scattered. Do not attempt lamp replacement yourself. Instead, contact an installer or Canon Customer

Support Center for internal cleaning, inspection, and lamp replacement.

• If you accidentally inhale gas from the lamp or get any pieces in your eyes or mouth, consult a doctor

immediately.

Take the following precautions when replacing lamps that stop working. Failure to do so may result in

injury.

• If illumination suddenly stops, either when you turn the projector on or during use, the lamp may have

ruptured. In this case, never attempt replacement yourself. Request replacement from an installer or

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.

Precautions for the Batteries of the Remote Control

Take the following precautions regarding handling of batteries. Failure to do so may result in a fire or

personal injury.

• Do not heat, short circuit or disassemble the batteries, or place them in a fire.

• Do not attempt to recharge the batteries that are included with the remote control.

• Remove the batteries when they are flat or when the remote control will not be used for a long period of

time.

• Insert the batteries with the + and - terminals in the correct directions.

• If any liquid from inside the batteries leaks out and contacts your skin, be sure to wash the liquid off

thoroughly.
