When "Please clean the filter. Have you
finished? Yes V No v" appears on the screen,
you should clean the air filter.
The air filter should be cleaned every 1250
hours. This value varies depending on the
environment or how the projector is used. 1250
hours are approximate.
1
Turn the power off and unplug
the power cord.
2
Place a protective sheet (cloth)
beneath the projector and turn the
projector over.
3
Remove the filter holder.
When the air filter cover (supplied) has
been attached because the projector is
installed on the ceiling, remove this air
filter cover before removing the filter
holder.
For detailed information on the air filter
cover, see "To attach the supplied air filter
cover for ceiling installation" (1 page
76).
4
Remove dust with a vacuum
cleaner.
Note
Be careful that the filter does not get
caught in the vacuum cleaner.
