When the projector is positioned upside down in a place such as a tall cabinet or shelf, follow the below.

•Place the projector on a flat and level surface.

•To avoid accidental button operation, stick the supplied three non-slip rubber pads on three locations on the projector top cabinet as shown in the drawing. They are a peel-and –sticker pad. Before use, peel the paper off the back of the rubber pad.
