2. Disconnect the projector from any cables.
3. Locate the filter case on the back of the
projector.
4. Release the filter case from the projector by
pressing the filter case into the slot slightly. The filter case

6. Use a small vacuum cleaner designed for
computers and other office equipment to clean the
filter sponge. Or use a soft brush (such as a clean
artist’s paintbrush) to gently sweep the dust on the
filter away.
If the dirt is difficult to remove or the filter is
broken, replace it with the supplied spare filter
sponge. See "How to replace the filter sponge:"
