Replacement Lamp Model No.: 23040049
LAMP HANDLING PRECAUTIONS
This projector uses a high-pressure lamp which must be handled carefully and properly.
Improper handling may result in accidents, injury, or create a fire hazard.
● Lamp life may differ from lamp to lamp and according to the environment of use. There is no
guarantee of the same life for each lamp. Some lamps may fail or terminate their life in a shorter
period of time than other similar lamps.
● If the projector indicates that the lamp should be replaced, i.e., if the WARNING indicator lights up,
replace the lamp with a new one IMMEDIATELY after the projector has cooled down. (Follow
carefully the instructions in the Lamp Replacement section of this manual.) Continuous use of the
lamp with the WARNING indicator lighted may increase the risk of lamp explosion.
● A Lamp may explode as a result of vibration, shock or degradation as a result of hours of use as its
lifetime draws to an end. Risk of explosion may differ according to the environment or conditions in
which the projector and lamp are being used.
IF A LAMP EXPLODES, THE FOLLOWING SAFETY PRECAUTIONS SHOULD
BE TAKEN .
If a lamp explodes, disconnect the projector's AC plug from the AC outlet immediately. Contact an
authorized service station for a checkup of the unit and replacement of the lamp. Additionally, check
carefully to ensure that there are no broken shards or pieces of glass around the projector or coming
out from the cooling air circulation holes. Any broken shards found should be cleaned up carefully.
No one should check the inside of the projector except those who are authorized trained technicians
and who are familiar with projector service. Inappropriate attempts to service the unit by anyone,
especially those who are not appropriately trained to do so, may result in an accident or injury caused
by pieces of broken glass.
