Routine Servicing

Clean dirt on the cabinet

with a soft cloth. In case of heavy soiling, soak a cloth in neutral detergent diluted with water, wring dry and wipe, followed by wiping again using a dry cloth.

Pay attention to the following to prevent the cabinet from deteriorating in condition, getting damaged, or the paint from coming off.

Do not wipe with a stiff cloth

Do not wipe with force

Do not wipe with thinner or benzene

Do not spray volatile chemicals like insecticide

Do not allow prolonged contact with rubber or plastic products

Remove dirt that is attached to the vent holes

using a vacuum cleaner. Wipe using a cloth if a vacuum cleaner cannot be used. Leaving dust attached may prevent adjustment of the internal temperature and result in malfunction of the projector.

Clean dirt on the lens

using commercial blowers or lens cleaning papers (for cleaning glasses and cameras).

Do not use fluid-type cleaning agents. This may lead to peeling of the surface coating film.

Lens surface is fragile. Avoid rubbing or knocking it.
