the projector.
Cleaning of the air-fi lter
Clean the air-fi lter frequently (about once a month). If the air-fi lter 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. Remove the fi lter cover from the projector.
• Pull the fi lter cover in the direction of the arrow while pushing
up the tabs on the bottom of the fi lter cover.
2. Remove the air-fi lter from the fi lter cover.
3. Wash the air-fi lter.
• Use water or diluted mild detergent to clean the air-fi lter. Rinse
the air-fi lter thoroughly and let it dry completely.
4. Attach the air-fi lter to the fi lter cover.
5. Attach the fi lter cover to the projector.
• Insert the tabs on the top of the fi lter cover in the projector, and
then push the fi lter cover in the direction of the arrow.
Important:
• If the air-fi lter is damaged or becomes extremely dirty, change it
with a new air-fi lter. Contact your dealer for a new air-fi lter.
• Use the dedicated air-fi lter only.
Caution:
Be sure to use the projector with an air-fi lter. If not, dust may get
inside the projector causing fi re 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.

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