Cleaning

You should clean the projector if it becomes dirty or if the quality of
projected images starts to deteriorate.
Attention
Turn off the projector's power before cleaning.

Cleaning the Projector's Surface

Clean the projector's surface by wiping it gently with a soft cloth.
If the projector is particularly dirty, moisten the cloth with water
containing a small amount of neutral detergent, and then firmly wring
the cloth dry before using it to wipe the projector's surface.
Attention
Do not use volatile substances such as wax, alcohol, or thinner to clean the
projector's surface. The quality of the case may change or become discolored.

Cleaning the Lens

Use a commercially available cloth for cleaning glasses to gently wipe
the lens.
Warning
Do not use sprays that contain flammable gas to remove dust and lint from
the lens. The projector may catch fire due to the high internal temperature
of the lamp.
Attention
Do not rub the lens with harsh materials or subject the lens to shocks, as it
can easily become damaged.
