Installation of both lamp modules (Lamp 1 and Lamp 2) is required to operate the projector in dual

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 LAMP 1 and/or LAMP 2 lighted may

 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:
 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.
