Toshiba 250 ユーザーズマニュアル

If you use the projector mounted on the ceiling,
ask the dealer to carry out the maintenance
such as cleaning.

The filter inside the air filter cover is the part
to shut out dusts or dregs.
Do not use the projector with the filter taken
off.
We recommend you clean the air filter
frequently. (The cleaning period is once per
50 hours approximately).

Slide the front cover rightward side for
about 3 mm, then the front cover can be
taken off toward you.

Take off the filter frame by pulling the
middle part of it toward you, then detach
the air filter.

Use a vacuum cleaner to carefully remove any dust and dirt from the front
cover, air filter and filter frame.
Be careful that the air filter is not sucked into the vacuum cleaner.
