If you place the projector below the level of the screen, you’ll
have to tilt it up by extending the adjustable front foot, as
shown below. This may cause the image to lose its rectangular
shape, but you can correct the distortion. (See page 6 for
detailed information about correcting the image shape.)
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 6 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.
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.
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.
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.
33.1 to 39.7 feet
6.6 to 7.9 feet
3.2 to 3.9 feet
Follow these steps to plug in and turn on the projector:
1. Remove the lens cap.
To calculate exact measurements, use the following formulas:
Caution:
Do not use the projector with the lens cap in place. The heat
generated by the lamp can damage the cap.
❏ To find the projection distance when you know the screen’s
diagonal dimension:
Wide (inches) = ((33.696 × diagonal screen size [inches]) –
21.717) / 25.4
Tele (inches) = ((40.453 × diagonal screen size [inches]) –
22.52) / 25.4
2. Connect one end of the power cord to the projector’s power
inlet. Then connect the other end to an electrical outlet.
The Power light on top of the projector turns orange,
indicating that the projector is in standby mode.
❏ To find how large a screen’s diagonal dimension will be
when you know the projection distance:
Wide (inches) = (Projection distance [inches] × 0.0254 +
0.02171) / 0.033696
Tele (inches) = (Projection distance [inches] × 0.0254 +
0.02252) / 0.040453

seconds for the projector to sync up after pressing the
button.)
Remote control
❏ If you’re using a PC notebook, see below.
The projector beeps once and the Power light flashes green
as the projector warms up, then an image begins to appear.
When the Power light stops flashing and remains green, the
projector is ready for use.
The Projector and Notebook Don’t
Display the Same Image
Warning:
Never look into the lens when the lamp is on. This can damage
your eyes, and is especially dangerous for children.
If you’re projecting from a notebook, and you can’t see your
image on the projection screen and on your computer at the
same time, follow these guidelines.
❏ 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’re using a PC notebook:
❏ On most systems, there’s a function key that lets you toggle
between the LCD screen and the projector, or display on
both at the same time. It may be labeled CRT/LCD or have
an icon such as
. You may have to hold down the Fn
key while pressing it. Allow a few seconds for the projector to
sync up after changing the setting.
❏ If you don’t see the image you want, press the Source
Search button on the projector or the Search button on
the remote control until you see the image you want to
project.
❏ If the function key doesn’t permit you to display
simultaneously on both screens, you should check your
monitor settings to make sure both the LCD screen and the
external monitor port are enabled.
❏ 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.
From the Control Panel, open the Display utility. In the
Display Properties dialog box, click the Settings tab, then
click Advanced. The method for adjusting the settings
varies by brand; you may need to click a Monitor tab, then
make sure the external Monitor port is set as your primary
display and/or enabled. See your computer’s documentation
or online help for details.
If a projected image fails to appear, see “You Can’t Project an
Image” 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.

until you are satisfied with the shape of the image.
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 Auto
button on the remote control or the Enter button on the
projector. This automatically resets the projector’s tracking,
sync, resolution, and position settings. (You must be projecting
an image for this button to have any effect.)
Note:
If the Auto Setup option in the Signal menu is set to OFF, the
Auto function will not work.
❏ Or press the Menu button on the remote control or
projector, select the Setting menu, and press Enter. From
the Setting menu, select Keystone and press Enter. Use the
pointer button on the remote control to adjust the
keystone setting as needed. The keystone setting is adjustable
from –65 to +65. These numbers represent a range of –30°
to +30° of angle change; adjustments are made in steps of
0.5°.
Adjusting the Image Shape
The projector automatically corrects images that are distorted
when the projector is tilted up or down (up to 30°). The
Keystone window appears on the screen while the projector
makes the correction.
After correction, your image will be slightly smaller.

Resizing Video images
❏ 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.
You can use the Resize button on the remote control to adjust
how an image fits into the display area.
For video images, press Resize to switch the aspect ratio
between 4:3 and 16:9. This lets you play certain digital video
images or movies recorded on certain DVDs in 16:9 widescreen
format.
❏ If your image looks like
or
, you may need to
manually adjust the keystone correction value. Follow the
instructions below.
For computer images, resizing is normally unnecessary, since
the projector automatically resizes the image to make the best
use of the display area. If you press the Resize button on the
projector or remote control, the projector displays the image at
the output resolution of the computer (which makes the image
larger or smaller, depending on its resolution). If the resolution
of the image is the same as the projector’s (1024 × 768),
pressing Resize has no effect.

Cleaning and Replacing the Air Filter
Replacing the Lamp
Clean the air filter and air vents on the bottom of the projector
after every 100 hours of use. If not cleaned periodically, they
can become clogged with dust, preventing proper ventilation.
This can cause overheating and damage the projector.
The projection lamp typically lasts for about 2000 hours of use
(in High Brightness mode) or 3000 hours (in Low Brightness
mode). It is time to replace the lamp when:
1. Turn off the projector, allow it to cool down, and unplug the
power cord.
❏ The

lamp light is flashing orange.
❏ The message Replace the Lamp appears on the screen when
the lamp comes on. To maintain brightness and image
quality, replace the lamp as soon as possible.
2. Turn the projector upside down.
Use a small vacuum cleaner designed for computers and
other office equipment. If you don’t have one, use a very soft
brush (such as an artist’s brush).
See page 25 for ordering information and request part number
V13H010L32.
Note:
You can check how many hours the lamp has been used in the Info
menu.

the life of the product.
Follow these steps to replace the lamp:
1. Press the P Power button twice to turn off the projector.

filters. See “Optional Accessories” on page 25 for ordering
information.
2. If the projector has been on, allow it to cool down for at least
an hour (or until the lamp is cool).
Warning:
Let the lamp cool before replacing it. In the unlikely event that
the lamp has broken, small glass fragments may be present and
should be removed carefully to avoid injury.
3. If you need to replace the filter, slide it off as shown.
3. Turn the projector over. Press in on the tabs and lift up the
lamp cover.
4. Slide the new air filter until it clicks in place.
