7. Maintenance

This section describes the simple maintenance procedures you should follow to replace the lamp, and to clean the cabinet and the lens.

￿Cleaning the Cabinet

1.Turn off the projector before cleaning.

2.Clean the cabinet periodically with a damp cloth. If heavily soiled, use a mild detergent. Never use strong detergents or solvents such as alcohol or thinner.

￿Cleaning the Lens

Use a blower or lens paper to clean the lens, and be careful not to scratch the lens.

Lens Protector

The lens barrel has threads on the outside for mounting a commercially available step-up ring (φ77mm → φ82mm) and lens protector (φ82mm) to protect the lens from dirt, dust, scratches and damage. Note that both a lens protector and the supplied lens cap cannot be used at the same time.

CAUTION: Use only transparent lens protectors designed for lens protection.

Use of filters for light reduction and special effects, such as ND (Neutral Density) filters and color filters, can absorb heat, resulting in damage to the filter and the projector.
