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
3.2 and 39.7 feet from the screen.
❏ Make sure there is plenty of space for ventilation around and
under the projector. Do not set the projector on top of
anything that could block the vents under the projector.
❏ Make sure the projector is within 10 feet of an electrical
outlet or extension cord and within 5 feet of your computer
and/or video source, unless you are projecting wirelessly or
from a memory card.
❏ 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.
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.
33.1 to 39.7 feet 6.6 to 7.9 feet 3.2 to 3.9 feet
To calculate exact measurements, use the following formulas:
❏ To find the projection distance when you know the screen’s
diagonal dimension:
Wide (inches) = ((33.696
21.717) / 25.4
Tele (inches) = ((40.453
22.52) / 25.4
❏ To find how large a screen’s diagonal dimension will be
when you know the projection distance:
Wide (inches) = (Projection distance [inches]
0.02171) / 0.033696
Tele (inches) = (Projection distance [inches]
0.02252) / 0.040453
× diagonal screen size [inches]) –
× diagonal screen size [inches]) –
× 0.0254 +
× 0.0254 +
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 you can correct the distortion by pressing
the
Sync buttons on the projector. See page 6 for detailed
information about correcting the image shape.
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 set up and
connected correctly. Then turn on your projector, as described
below.
If you turn on your connected 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 connected equipment, you may have
to select the image source manually. See “Selecting the Image
Source” on page 5.
Follow these steps to plug in and turn on the projector:
1. Remove the lens cap.
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.
The P
Power light on top of the projector turns orange,
indicating that the projector is receiving power but not yet
turned on.

3. Press the P
Power button on top of the projector or on the
remote control.

The projector beeps once and the P
Power light flashes
green as the projector warms up, then an image begins to
appear. When the P
Power light stops flashing and remains
green, the projector is ready for use.
Warning:
Never look into the lens when the lamp is on. This can damage
your eyes, and is especially dangerous for children.
❏ If you’ve connected a Windows
®
-based computer to the
projector, you may see a New Hardware Wizard saying
your computer has found a plug-and-play monitor; if so,
click
Cancel.
❏ If you don’t see the image you want, press the
Search button on the projector or the Search button on
Source
the remote control until you see the image you want to
project.
❏ If you are prompted to enter a password, see “Starting the
Projector with a Password” on page 10.
Note:
You can also use the Source buttons on the remote control to
switch between devices connected to the ports identified on each
button. For details, see page 5.
If a projected image fails to appear, see “What To Do If You See
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.
What To Do If You See a Blank Screen
If you see a blank screen or the No Signal message after turning
on your computer or video source, try the following:
❏ Make sure the cables are connected correctly.
❏ Make sure the P
the lens cover is off.

enabled. See your computer’s documentation or online help
for details.

After you select a source, the screen goes dark for a moment
before the image appears.
Adjusting the Image
Once you see your image, you may need to make certain
adjustments, as described in this section.
Focusing and Zooming Your Image
Rotate the focus ring to sharpen the image.
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
If the image is too low, you can raise it by extending the
projector’s front adjustable foot.
1. Stand behind the projector. Press up on the blue foot release
lever and lift the front of the projector to extend the front
adjustable foot.
2. Once the image is positioned where you want it, release the
lever to lock the foot in position.
3. If the projector is not level, rotate the
foot at the back of the projector.
If the image is no longer rectangular after
raising it, see the next section.

Correcting Computer Images
If you’ve connected a computer and the image doesn’t look
right, or it doesn’t fit properly on the screen, press the
button on the remote control or the
Enter button on the
projector. This automatically resets the projector’s tracking,

Adjusting the Image Shape
The projector automatically corrects images that are distorted
when the projector is tilted up or down (up to a 15° tilt). The
Keystone window appears on the screen while the projector
makes the correction. If the projected image still isn’t
rectangular or has a “keystone” shape, do one or more of the
following:
❏ If your image looks like or , you’ve placed the
projector off to one side of the screen, at an angle. Move it
directly in front of the center of the screen, facing the screen
squarely.
❏ If your image looks like or , you may need to
manually adjust the keystone correction value. Follow the
