16 Setting Up the Projector
Positioning the Projector
If you’re setting up the projector yourself
and it isn’t already installed in the theater
or conference room you’re using, you’ll
probably want to place it on a table in front
of the screen, as shown. a
This lets you stand in the front of the
room, face the audience, and remain
close enough to the equipment to be able
to control it. Try to leave as much space as possible between the
projector and the screen to get a good-size image.
Use the figure below to help you determine placement. Image size
increases with distance, but can vary depending on how you’ve
adjusted the optical zoom and other settings. (For detailed calculations
for the lens you are using, see page 18.)
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 10 feet of a grounded electrical
outlet or extension cord.
note
You can mount the projector
on the ceiling, or place it
behind a translucent screen
for rear projection. See
page 119 for details.
