2 . Place the projector the correct distance from the screen. The distance between the projector and the screen
determines the actual size of the image.

3 . Position the projector so that the lens is set at a right angle to the screen. If the projector is not set at a right angle,
the screen image will be crooked. If this is so then the keystone adjustment may correct this (Refer to page 49.)
