Positioning the Image If the image is not centered on the screen, use the horizontal and vertical lens shift dials to adjust its position. 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. Horizontal lens shift dial Vertical lens shift dial Adjustable foot Note: You can display a test pattern to help adjust the image position. Press the Pattern button on the remote control, then select Display Position. When you hear a click, the lens position is centered. If the lens shift dial becomes hard to turn, you cannot adjust the position any further. If you still need to raise the height of the image after using the vertical lens shift dial, lift the front of the projector and rotate the adjustable feet until the image is positioned correctly. 24 Setting Up the Projector
