Appendix A. Maintenance

This chapter provides information on projector maintenance.

Cleaning the projector

Cleaning the projector to remove dust and grime will help ensure trouble-free operation.

vBe sure to turn off and unplug the projector at least 1 hour before cleaning. Failure to do so could result in a severe burn.

vUse only a dampened cloth when cleaning. Do not allow water to enter the ventilation openings on the projector.

vIf a little water gets into the projector interior while cleaning, leave it unplugged in a well-ventilated room for several hours before using.

vIf a lot of water gets into the projector interior when cleaning, have the projector serviced.

Cleaning the lens

To clean the lens, complete the following procedure:

1.Apply a non-abrasive camera lens cleaner to a soft, dry cloth.

Note: Avoid using an excessive amount of cleaner, and do not apply the cleaner directly to the lens. Abrasive cleaners, solvents or other harsh chemicals might scratch the lens.

2.Lightly wipe the cleaning cloth over the lens in a circular motion. If you do not intend to use the projector immediately, replace the lens cap.

Cleaning the case

Follow the steps below to clean the projector case:

1.Wipe off dust with a clean dampened cloth.

2.Moisten the cloth with warm water and mild detergent (such as dish detergent), and wipe the case.

3.Rinse all detergent from the cloth and wipe the case again.

Note: To prevent discoloration or fading of the case, do not use abrasive alcohol-based cleaners.

Replacing the projector lamp

The projector lamp should only be replaced with an IBM certified replacement part, which you can order from your business partner or go to www.ibm.com/pc.

To replace the projector lamp, complete the following procedure:

1.Turn off the projector, unplug the power cord, and allow the projector to cool for at least 1 hour.
