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.
