Setting Up the Projector

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.
Note: You can display a test pattern to help adjust the image position by pressing the Pattern
button on the remote control. Select Display Position, then press Enter. Press the Esc button to
turn off the test pattern. You can also use the Pattern button to isolate colors when displaying
color bars (see page 39).
When you hear a click, the lens position is almost centered. If the lens shift dial becomes
difficult to turn, you cannot adjust the position any further.
If one side of the image is taller than the other, make sure the projector is parallel to the
screen. If necessary, adjust the front feet so that the projector is horizontal.
