WARNING ►Do not replace the air filter during use or immediately after use.
Handling while the projector is in a high temperature could cause a burn and/or
malfunction to the projector. Before operating, make sure that the power switch is off,
that the power cord is not plugged in, and that the projector is cool adequately.
►Use only the air filter of the specified type. Do not use the projector with the air filter
and filter cover removed.
►Avoid wetting the projector or inserting liquids in the projector. It could result in a
fire, an electric shock, and and/or malfunction to the projector.
CAUTION ►Please replace the air filter when it is damaged or too soiled, and also
when you replace the lamp.
When the indicators or a message prompts you to clean the air filter, clean the air filter as
soon as possible. If the air filter becomes clogged by dust or the like, internal
temperatures rise and the power may be automatically turned off for malfunction
prevention.
