Maintenance

Cleaning the lens

1 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.

2 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.

Using the security lock

The projector has a security lock for use with a cable lock system. See

“Accessories” on page 43 for ordering information. Refer to the information

that came with the lock for instructions on how to use it.
