Ideally, keep the projector level and place it at a height so its lens is centered between the top and bottom of the screen, as shown below. If this is not possible, you can use the lens shift dials to reposition the image. As a rule of thumb, you can use lens shift to move the image up or down by nearly its full height, and left or right by about one-half its width (for details, see page 26).

If you place the projector off to the side, aim it straight ahead (rather than at the center of the screen), then use the horizontal lens shift dial to center the image on the screen.

Caution: Do not try to move the lens by hand, or you may damage the projector. Always use the lens shift dials to change the lens position.
