Attention
zMake sure that the projector power supply is switched off before attaching or detaching the
projection lens.

of the lens will be magnified by the lens and lower the quality of the projected image. Place
the supplied lens cover on the zoom lens when the projector is not in use.

Do not use fluffy cloths containing oil, water or dust for cleaning. The lens is easily
damaged, so do not apply excessive pressure when wiping it.
