Cleaning

Cleaning the Cabinet and the Lens
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.
3. Use a blower or lens paper to clean the lens, and be careful not to
scratch or mar the lens.

Lens Protector

The lens barrel has threads on the outside for mounting a commercially
available lens protector ( 82mm) 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.
