Setting Up the Projector
Positioning the Projector
Before connecting the projector, you need to decide where to place it.
The location you choose depends on the size of the room and what
you are projecting.
■ Place the projector on a sturdy, level surface, between
3.6 and 47.6 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 your computer
and/or video source.
■ Place the projector directly in front of the center of the screen,
facing it toward the screen squarely. Otherwise, your image will
not be square.
Most presenters find it convenient to place the projector in front of
the audience, leaving as much space as possible between the projector
and the screen to get a good-sized image. This lets the presenter stand
in the front of the room, face the audience, and remain close enough
to the equipment to be able to control it.
Use the figure below as a guideline to help you determine how far
from the screen to place the projector. Image size generally increases
with distance, but may vary depending on how you position the zoom
ring and whether you have adjusted the image size with other settings.
The dimensions shown are based on using the standard lens.
caution
Don’t hold or lift the
projector by the lens, or
you may damage it.
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 correctly at the
screen and get a square
image.
