The following section explains how to clean the air filter on the side of the projector.
The air filter prevents dust and dirt from entering the interior of the projector.
If the message "Check the air filter for dirt." is displayed, check the air filter for dirt or dust, and
use the following procedure to clean off any dirt or dust.
・Either of the following may occur if the air filter is clogged and the interior of the projector
overheats due to inadequate air circulation. If this is the case, clean the air filter.

5. Attach the intake vent cover to the projector.
Insert the intake vent cover from its bottom to the opening on the projector, and then close
the cover by pushing the tab at the top of the cover.
Make sure that the intake vent cover is installed correctly. Otherwise, dirt and dust may enter
the projector through any gaps and cause it to stop or malfunction.
The message is displayed for approximately 30 seconds every 500 hours after the
projector is first turned on. The display closes when operation starts.
Depending on the environment in which the projector is located, the filter may get
clogged earlier than expected. When any dust or dirt has visibly collected on the air filter,
clean it regardless of whether the warning message is displayed or not. A buildup of dust
on the air filter may cause poor ventilation, causing the interior of the projector overheat
and operations to stop or malfunction.
