To project images from a computer, set the computer’s video
card at a refresh rate (vertical frequency) compatible with the
projector; see the following table for compatible formats. For
best results, set the computer’s resolution to the projector’s
native resolution (1024 × 768). If this resolution isn’t available,
select one of the other compatible formats.

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
2.8 and 48.3 feet from the screen.
❏ Make sure there is plenty of space for ventilation around and
under the projector. Leave at least 8 inches between the
projector and a wall.
❏ Make sure the projector is within 6 feet of an 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 the screen squarely. Otherwise, your image
will not be rectangular.
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 rectangular image.
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.
29.8 to 48.3 feet 5.8 to 9.5 feet 2.8 to 4.7 feet
If you place the projector below the level of the screen, you’ll
have to tilt it up by extending the front adjustable foot, as
shown. Tilting the projector upward causes the image to lose its
rectangular shape, but the Auto Keystone feature corrects the
distortion automatically. If the image does not regain its
rectangular shape, the Auto Keystone feature may have been
disabled. To turn it on, see page 6.
If you place the projector level with the bottom of the screen,
the image will be rectangular and you won’t have to adjust it. If
you place the projector higher than the bottom of the screen,
the image will still be rectangular, but you won’t be able to fill
the whole screen with the image.
Starting Up the Projector
Make sure your projector and other equipment are connected
correctly. Then turn on your projector, as described below.
If you turn on your computer or video equipment before
starting the projector, the projector automatically detects and
displays the image source. If you turn on the projector first or
have multiple pieces of equipment connected, you may have to
select the source manually. See page 5.
1. Remove the lens cap.
To calculate measurements, use the following formulas:
❏ To find the projection distance when you know the screen’s
diagonal dimension:
Wide (inches) = ((Diagonal screen size [inches]
× 2.97334) –
2.3937) / 2.54
Tele (inches) = ((Diagonal screen size [inches]
× 3.61474) –
2.06831) / 2.54
❏ To find how large a screen’s diagonal dimension will be
when you know the projection distance:
Wide (inches) = (Projection distance [inches]
× 0.32827 ×
2.54) + 1.6767
Tele (inches) = (Projection distance [inches]
× 0.203 × 2.54)
+ 1.077
Caution:
Do not use the projector with the lens cap in place. The heat
generated by the lamp can damage the cap.
2. Connect one end of the power cord to the projector’s power
inlet. Then connect the other end to an electrical outlet.

a Blank Screen” in the next column.
When you’re done with your presentation, shut down the
projector as described on page 7. Shutting down the projector
correctly prevents premature lamp failure and possible damage
from overheating.

Selecting the Image Source
If multiple devices are connected to the projector, the easiest
way to select the image source is to press the
button on either the projector or remote control until the
correct image is projected.
You can also press one of the following buttons on the
remote control:

Computer 1/Component Video 1 port.
❏
Comp 2 button to select the device connected to the
Computer 2/Component Video 2 port.
❏
S-Video to select the device connected to the
S-Video port.
❏
Video button to select the device connected to the
Video port.
After you select a source, the screen goes dark for a moment
before the image appears. The name of the selected source (such
as
Computer1 (Auto) or S-Video) appears briefly on the
screen.
Source Search
You can also change the image size by moving the projector
closer to or farther away from the screen. You can use the
E-Zoom buttons on the remote control to zoom in on a portion
of the image. See “Zooming Your Image” on page 7 for
instructions.
Adjusting the Height of Your Image
