Cleaning the Projector
Make it a habit to clean the projector at regular intervals as described in this section. Before cleaning 
the projector, be sure to unplug it from the power outlet and make sure it is cooled down completely.
Wipe the exterior of the projector with a soft cloth that has been moistened in a weak solution of water 
and a mild neutral detergent. Be sure to wring all excess moisture from the cloth before wiping.
Never use benzene, alcohol, thinner, or any other volatile agent for cleaning.
Carefully wipe the lens with a commercially available lens cloth or optical lens paper, like those for 
eyeglasses or camera lenses. When cleaning the lens, do not apply undue force and take care to avoid 
damaging the lens.
Dust and dirt tend to collect around the intake vents. Because of this, you should use a vacuum 
cleaner to clean away accumulated dust and dirt periodically (about once a month) as shown below.
Important!Continued use of the projector after dust has accumulated around the intake vents can cause 
overheating of internal components and lead to malfunction.
Certain operating conditions also can cause dirt and dust to accumulate around the 
projector’s exhaust vents. If this happens, use the same procedure as that described above to 
clean the exhaust vents.
