a dry cloth.

deteriorate the outer case.

Lens front surface
Wipe off dirt and dust from the front surface of the lens with a soft clean cloth.
f Do not use a cloth that is fluffy, dusty, or soaked with oil/water.
f Since the lens is fragile, do not use excessive force when wiping the lens.
Attention
f The lens may become damaged by hitting with a hard object or by wiping the front surface of the lens with excessive force. Handle with
care.
Note
f Dust may accumulate around the air intake/exhaust port depending on the environment and operating condition when used in an
environment with excessive dust. This may adversely affect the ventilation, cooling, and heat dissipation inside the projector, thus causing
reduced brightness.
