Casio Computer Co Ltd XJH1750 Manuale Utente

Periodically clean the projector exterior, lens, intake vents, and intake-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, do not apply undue force and take care to avoid 
damaging the lens.

Dust and dirt tend to collect around the vents. Because of this, you should use a vacuum cleaner to 
clean away accumulated dust and dirt periodically as shown below.

Important!

z Continued use of the projector after dust has accumulated around the vents can cause 

overheating of internal components and lead to malfunction.
