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. Loosen two screws that are fi xing the right side panel using a
Phillips screwdriver (+) and remove the panel from the projector.
2. Remove the fi lter from the right side panel.
(1) Remove the holder by pushing the tab of the holder on the air-
fi lter in the direction of the arrow.
(2) Remove the air-fi lter (white), spacer, and air-fi lter (gray).
3. Clean dirt and dust adhering to the air-fi lter using a vacuum.
• For the air-fi lter (white)
If stubborn stains persist, wash the air-fi lter with water
and dry well in the shade.
• For the air-fi lter (gray)
If stubborn stains persist, wash the air-fi lter with diluted
detergent, rinse with water, and dry well.
4. Attach the fi lter to the right side panel.
(1) Attach the air-fi lter (gray), spacer, and air-fi lter (white) to the
side panel, aligning their notches with that of the side panel.
(2) Insert the right tab of the holder to the side panel and push the
left tab in the direction of the arrow to attach the side panel.
5. Attach the right side panel to the projector and fi x it with two
screws.
Important:

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.
• 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 fl uid. The lens surface is
fragile. Use only recommended, nonabrasive lens-cleaning materials. Do not touch the lens with your fi ngers.
