Maintenance 49
A warning message like the one pictured to the
right will be displayed for 10 seconds every 300
hours of use to remind you to clean the filters.
IMPORTANT: Please ensure that the projector is
properly shutdown before removing the filters
for cleaning or replacement.
This projector has two concealed filters. One is
fitted behind the front vent grill (see item 7 on
page 11), and the other is on the left side (see item 16 on page 11).
Front filter
1A. Access to the front dust filter is located on the right side of the projector towards the
front edge. Use your thumb or finger to pull it out from the side as illustrated in
diagram 'A' below.
1B. If the front filter proves difficult to remove, you should use a broad flat implement
(like an ice-cream stick) to gently lever the filter away from the projector case as
illustrated in diagram 'B' below.
1C. Carefully pull the filter cartridge out from the side of the projector while keeping it
parallel with the front as illustrated in diagram 'C' below
Rear filter
2. Access to the rear dust filter is located on the left side of
the projector towards the rear. Use your thumb or finger
to pull it out from the side as illustrated below.
3. To clean the filters, use a small vacuum cleaner
designed for computers and other office equipment,
or use a soft brush (such as a clean artist's
paintbrush) to gently sweep the dust away. Refit and
align the filter sponge to sit snugly within the filter
frame for the front filter, so that no obvious gaps are
visible around the edges between the edge of the filter
sponge and the plastic filter frame housing.
If the dirt is difficult to remove or the filters are
broken, replace them. Contact your dealer or visit BenQ website at www.BenQ.com
for more service information.
4. Carefully refit the filters to the projector then press the covers back until they click into
place.
If the covers are not correctly seated in place, you will be reminded by a message
displayed on the screen every three minutes. The projector will automatically shut
