Maintenance

Warning:

Do not use flammable solvents (benzene, thinner, etc.) and flammable aerosols when cleaning the projector body and lens. Flammable substances may ignite causing fire or breakdown while the lamp is illuminating.

Caution:

Be sure to turn off the lamp and unplug the power cord from the wall outlet before you perform any maintenance on the projector.

Cleaning of the projector and the ventilation slots

Use a soft cloth to clean the projector and the ventilation grilles. When the grilles become dirty, wipe them with a soft cloth dampened with diluted mild detergent, and then wipe them with a dry cloth.

To protect the surface of the projector from fading or deteriorating:

Do not spray insecticide on or inside the projector.

Do not use benzin or thinner to clean it.

Do not let rubber or plastic materials contact with projector.

Cleaning of the lens

Remove dust or dirt using the commercially available lens care products (such as cleaning paper or cloth for lens and blower brush).

Since the lens surface is sensitive, do not scrub it with a solid object or tap on it.

Do not wipe the lens with a lens cleaner. It may cause wipe marks or peel of the lens coating.
