Projector Placement Guidelines
To get the best results when projecting your images, position
the projector at the proper height and distance relative to the
screen. When projecting from a table or desk, place the
projector so the lens is aligned as closely as possible with the
bottom of your screen:
When projecting from the ceiling, align the lens as closely as
possible with the top of your screen:
The distance between the projector and the screen determines
the actual image size. To determine the exact distance required
for a particular image size (or to determine the size of an image
at a particular distance), use the following formulas.
(Remember that the size of the image can be changed by
rotating the zoom ring.)
To determine the minimum and maximum diagonal size of an
image when you know the projection distance:
Inches:
Maximum image size = (0.6038 projection distance) + 1.8898
Minimum image size = (0.4631 projection distance) + 1.4000
Centimeters:
Maximum image size = (0.6038 projection distance) + 4.8001
Minimum image size = (0.4631 projection distance) + 3.5560
To determine the projection distance when you know the
diagonal size of the screen image:
Inches:
Maximum projection distance = (2.1593 image size) – 3.0229
Minimum projection distance = (1.6562 image size) – 3.1291
Centimeters:
Maximum projection distance = (2.1593 image size) – 7.6782
Minimum projection distance = (1.6562 image size) – 4.2068

For example, here are the measurements for three
installations:
Image size
(diagonal)
300 inches*
(762 cm)
200 inches
(508 cm)
100 inches
(254 cm)
*
For an image size of 300 inches, the projector may be up to 53.7 feet
away from the screen, depending on the setting of the zoom ring.
Using the Remote Control
The remote control uses a line-of-sight infrared signal. To use
the remote control, point it toward the infrared receiver
located at the front of the projector.
To be able to use the remote control as a cordless mouse,
connect the projector to your computer with the mouse cable
(PS/2 or ADB-Macintosh) that came with the projector.
You can use the remote control up to about 32.8 feet
(10 meters) from the projector. (This distance may be shorter
if the remote control batteries are low.) You must also hold the
remote control so that it is within
15 higher or lower than, the infrared receiver.

Note: If the projector doesn't respond to remote control
commands, a strong light source (such as direct sunlight) may be
hitting the infrared receiver. The presence of a certain type of
fluorescent light or equipment emitting infrared energy (such as a
radiant room heater) can also interfere with the transmission of
remote commands.
