Casio XJ-A250V User Manual

Periodically clean the projector exterior, lens, intake vents, and exhaust vents on a regular basis.

Important!

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, be very careful to avoid scratching it.

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 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 on the front. If this happens, use the same procedure as that 
described above to clean the exhaust vents.
