 Lamp Handling Precautions
 
This projector uses a high-pressure lamp whic h 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 accordin g to the environment of use. There is no guar-
antee 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 LAMP 1 and/or LAMP 2 light up, 
replace the lamp with a new one IMMEDIATELY a fter the projector has cooled down. (Follow care-
fully the instructions in the Lamp Replacement sect ion of this manual.) Continuous use of the lamp 
with LAMP 1 and/or LAMP 2 lighted may  increase the risk of lamp explosion. 
•  A Lamp may explode as a result of vibration, shoc k 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 condi-
tions in which the projector and lamp are being used. 
If a lamps explodes, the following safety precautions should be taken: 
Disconnect the projector’s AC plug from the AC outle t 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 projec tor 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 pro-
jector except those who ar e 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 inju ry caused by pieces of broken glass.
