Maintenance

Warning:

•Never use flammable air duster or other materials when cleaning the air-filter. Flammable substances may ignite causing fire or backdown when the lamp is illuminated.

•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 air-filter

Clean the air-filter frequently (about once a month). If the filter or ventilation grilles become clogged with dirt or dust, the temperature inside the projector may rise and cause troubles, such as damage to the inside parts and shortening the life of the panels.

•When the temperature inside the projector rises, the STATUS indicator will blink orange and the lamp will be turned off.

1. Raise the lock of the filter cover in the direction of the arrow.

2. Remove the air-filter.

3. Wash the air-filter or change it with a new filter.

Filter cover

• Use water or diluted mild detergent to clean the filter. Rinse the filter thoroughly and let it dry completely.

4. Attach the air-filter.

Air-filter

5.Attach the filter cover to the projector.

•Make sure that the air-filter is attached correctly without displacement.

Important:

•If the filter is damaged or becomes extremely dirty, change it with a new filter. Contact your dealer for a new filter.

•Use the dedicated filter only.

Caution:

Be sure to use the projector with an air-filter. If not, dust may get inside the projector causing fire and failure.

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 benzine or thinner to clean it.

•Do not let rubber or plastic materials contact with projector.

Cleaning of the lens

Use a standard lens-cleaning brush or a piece of lens tissue dampened with lens cleaning fluid. The lens surface is fragile. Use only recommended, nonabrasive lens-cleaning materials. Do not touch the lens with your fingers.
