The air filter prevents dust and debris from getting inside the projector. Never run the
projector with the filter removed. It is recommended that the air filter is cleaned regularly.
• The icon message
“Check the air filter for dirt.” is displayed every 100 hours. (If the
usage time exceeds 100 hours, this message is displayed for 30 seconds when the image is
displayed for the first time after power is turned on. This display will be dismissed with any
operation.)
• Check out the filter and any debris is found, use the following procedure for cleaning.
WARNING
• Request cleaning and maintenance of a ceiling-mounted unit from your projector
dealership.
1 Unplug AC power cord.
2 Remove the air filter.
Pull out the air filter by taking the catch shown in the figure.
3 Clean the filter.
Carefully remove the dust and dirt from the air filter with a
vacuum cleaner or the like.
4 Replace the air filter.
Notes
• Allowing dirt and dust to build up in the air filter will worsen the air circulation inside the
projector, causing the internal temperature to rise, causing the projector to stop working
or malfunction.
• Insert the air filter all the way in. Leaving gaps will allow dust and dirt to get inside the
projector again.
• If you wash the air filer with water, make sure to dry it completely before replacing it.
• If the air filter is torn, consult with your dealer about replacing it with a new one.
Continuing to use a ripped filter will allow dust and dirt to get inside the projector.

• If the lamp should break, please handle with care to avoid injury due to broken pieces
and contact your dealer for repair service.
