Important Operating Considerations
Do not place the projector on a tablecloth or other soft covering that may
block the vents. Vents are placed along the left and right sides of the
CD-850m, as well as across the front of the projector. Do not use a non-
approved ceiling mount. In the unlikely event of the lamp rupturing, dis-
card any edible items placed in the surrounding area and thoroughly clean
the area along the sides and in the front of the projector.
