Maintenance

Cleaning the lens

Apply 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.

Lightly 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.
