If the air filter becomes clogged by dust or the like, internal temperatures rise and
could cause a fire, a burn and/or malfunction to the projector. When the indicators
or a message prompts you to clean the air filter, clean the air filter as soon as
possible.
Please check and clean the air filter periodically, even if there is no message.
Please replace the air filter when it is damaged or too soiled. Preparation of a new
air filter is recommended.
To obtain a new air filter, please contact ViewSonic for the air filter part number.
When you replace the lamp, please replace the air filter. An air filter of specified
type will come together with a replacement lamp for this projector.

Turn the projector off, and unplug the

hand, use your other hand to pull the filter
cover forward in the direction of the arrow.
