Periodically clean the projector exterior, lens, intake vents, and exhaust vents on a regular basis.
Cleaning Intake and Exhaust Vents
Dust and dirt tend to collect around the intake vents located on the back and both sides of the
projector. Because of this, you should use a vacuum cleaner to clean away accumulated dust
and dirt periodically.
z Continued use of the projector after dust has accumulated around the intake vents can
cause overheating of internal components and lead to malfunction.
z Certain operating conditions also can cause dirt and dust to accumulate around the
projector’s exhaust vents on the front. If this happens, use the same procedure as that
described above to clean the exhaust vents.
Use the following procedure to replace the lens cover if it should accidentally become detached
from the projector.
1. Insert the nub (
1
) of the tab under the lens into the depression (
3
) of the left tab
of the lens cover.
z When performing the above step, make sure that the lens cover is open to 90 degrees in
relation to the front of the Data Projector.
2. Keeping the left nub (
1
) in the left depression (
3
), gently press the lens cover
towards the right as you insert the nub (
2
) of the right tab under the lens into the
depression (
4
) of the right lens cover tab.
z Do not apply undue force to the lens cover when performing the above step. Pressing too
strongly can damage the tabs of the lens cover.
