Maintenance and Cleaning

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 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.
