Positioning the Projector

Follow these guidelines to get the best results when projecting:
Place the projector on a sturdy, level surface, between
3.6 and 48 feet from the screen.
Make sure there is plenty of space for ventilation around and
under the projector.
Make sure the projector is within 10 feet of a grounded
electrical outlet or extension cord and within 5 feet of the
image source.
Face the projector squarely toward the screen. Otherwise,
your image won't be square.
Note: It's easier to position the projector when the screen is
directly in front of the room. If the screen is placed diagonally in a
corner, it's much more difficult to aim the projector squarely at
the screen and get a non-distorted image.
If you place the projector below the level of the screen, you'll
have to tilt it up by extending the feet as shown. Tilting the
projector upward causes the image to lose its square shape, but
you can correct the distortion by pressing the
button as described on page 6.
