Maintenance

NOTE: When you are performing maintenance activities on your projector, keep in mind that you should only remove screws that are single-slot, or flathead, screws. Any other type of screw, such as a phillips or star should not be removed. These types of screws should only be removed by technical support experts.

Cleaning the lens

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

Avoid using an excessive amount of cleaner, and don’t apply the cleaner directly to the lens. Abrasive cleaners, solvents or other harsh chemicals might scratch the lens.

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