Important Information
LAMP HANDLING
PRECAUTIONS
This projector uses a high-pressure mercury lamp which must be handled carefully and properly as mentioned below.•A  lamp may explode with a loud sound or burn out due to a shock, scratch, or expiration of lifetime.
• The lamp life may differ from lamp to lamp and according to the environment of use. There is not guarantee of the
same lifetime for each lamp. Some lamps may fail or terminate their life in a shorter period of time than other
similar lamps.
•A  lamp gradually becomes darker with time of use.
• If the projector indicates that the lamp should be replaced (i.e., the LAMP indicator blinks red rapidly), chances of
explosion become higher. Replace the lamp with a new one immediately.
• Always keep your face away from the exhaust vent so that you do not suffer from the gas and broken shards of the
lamp.
IF A LAMP EXPLODES
If a lamp explodes, the gas and broken shards may scatter inside the projector and they may come out
of the exhaust vent. The gas contains toxic mercury.
Open windows and doors for ventilation.
If you inhale the gas or the shards of the broken lamp enter your eyes or mouth, consult the doctor
immediately.
If a lamp explodes, its shards may scatter inside the projector. Ask the Canon service representative to
clean and check the inside of the projector and replace the lamp.
DISPOSAL OF WASTE LAMP
Dispose of the mercury lamp of the projector according to the local regulation just like the fluorescent
lamp.
Lamp Replacement
•T o replace the lamp, follow all instructions provided on page  50 .
• Be sure to replace the lamp when the message  [Replace with the new lamp.] appears. If you continue to use
the lamp after the lamp has reached the end of its usable life, the lamp bulb may shatter, and pieces of glass
may be scattered in the lamp case. Do not touch them as the pieces of glass may cause injury.
If this happens, contact your dealer for lamp replacement.
CAUTION
When removing the lamp from a ceiling-mounted projector, make sure that no one is under the projec-
tor. Glass fragments could fall if the lamp has been burned out.
