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.

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:
