Maintenance

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 Filter cover

Clean the air-filter fre- quently (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.	Put the projector upside	Lock
	down and 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.

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

4. Attach the 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.

•The projector will not turn on if the air-filter cover is attached improperly .

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 ventila- tion grilles. When the grilles become dirty, wipe them with a soft cloth dampened with diluted mild deter- gent, 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, nonabra- sive lens-cleaning materials. Do not touch the lens with your fingers.
