Lamp Handling Precautions; How To Check Lamp Used Time - Sanyo PLC-XF47 Service Manual

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 owner's 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, 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.
