In this example the projector is upside down with the lens shift maximum position.
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.
