16 Setting Up the Projector
Also keep these considerations in mind:
■ Place the projector on a sturdy, level surface.
■ Make sure there is plenty of space for ventilation around and
under the projector. Do not set the projector on top of loose
papers that could block the vents under the projector.
■ Make sure the projector is within 2 m of a grounded electrical
outlet or extension cord.
Try to place the projector directly in front of the center of the screen,
facing it toward the screen squarely. If the projector isn’t positioned
this way, the image will be “keystone” shaped, instead of rectangular.
If you place the projector below the level of the screen, you’ll have to
tilt it up by extending the front adjustable foot (see page 38). If you
mount the projector on the ceiling, you’ll need to adjust its position
using the ceiling mount. This also causes the image to lose its
rectangular shape. You can adjust the shape using the buttons on the
projector (see page 39) or the projector’s menu system (see page 59).
Other Installations
You can also project from behind the screen or from the ceiling, with
the projector mounted upside-down:
To project from overhead, you’ll need the optional ceiling mount
hardware. (See page 13 for ordering information.) You’ll also need to
select
Front/Ceiling or Rear/Ceiling for the Projection option in the
Extended menu. To project from the rear, select
Rear. See page 61 for
more information.
