A warning message like the one pictured to the
right will be displayed for 10 seconds every 500
hours of use to remind you to clean the filter. To
leave the message, press ENTER on the projector or
remote control.
To clean the filter
1. Turn the projector off and wait until the fans
stop running.
2. Locate the filter case on the back of the
projector.
3. Release the filter case from the projector by
pressing the filter case into the slot slightly. The filter case
springs out of the slot.
4. Pull out the filter case.
5. 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 "Replacing the filter sponge" next
page.
