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 lifetime may differ from lamp to lamp and according to the environment of use. There is no guarantee of the
same lifetime for each lamp. Some lamps may fail or terminate their lifetime in a shorter period of time than other
similar lamps.
● If the projector indicates that the lamp should be replaced, i.e., if the LAMP REPLACE 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 LAMP REPLACE 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.
