SETTING UP THE PROJECTOR
Setting Up the Projector
Determining the Distance to the Screen
The projected image size is determined by the distance between the projector lens and the
screen. Select the place where the desired image size is obtained according to the illustra-
tion shown below.
H1 and H2: The height of the screen from the intersection of optical axis and screen surface when an
image is projected at right angle to the screen.
zInstall the projector at the position where the projection distance is between approxi-
mately 1.2 m (3.9) to 9 m (29.5). If the installation position is too close or too far, the
image is out of focus or the screen becomes dark, respectively.
zThe sizes in the above table have been obtained assuming that the aspect ratio is 4:3.
They may vary from the actual sizes depending on the type of the projected image.
zSelect the appropriate setting for [Screen aspect] with respect to the your screen (4:3
or 16:9).
Refer to pages 59, 74, and 101 for more detailed information on [Screen aspect].

SETTING UP THE PROJECTOR
Determining the Installation Position
Placing in Front of the Screen
Place the projector perpendicular to the screen
as far as possible.
Placing on a Level Place
Place the projector on a level place as far as pos-
sible.
zA slight error in the projection angle can be
corrected using the [KEYSTONE] button
(P52).
zA slight tilt can be corrected using the rear
adjustable foot. (P43)
zMake sure that the installation position is
free from any obstacle that may block the
exhaust vent (fan) on the right side of the
projector and the air intake vent on the bot-
tom of the projector.
zThe screen must not be exposed to direct
sunlight or light from lighting equipment. In a
bright room, it is recommended to limit
ambient lighting in order to improve the
image quality.

Ceiling Mounting or Rear Projection
You can mount the projector on the ceiling (Ceiling mounted) with it turned up side
down or place it behind the screen (Rear) if you use a translucent screen. For ceiling
mounting or rear projection, you have to invert the projected image. (P97).

PROJECTING AN IMAGE FROM THE COMPUTER
zBefore connecting cables, turn off both the projector and computer.
z It may project an image inappropriately when projecting the digital PC signal in 1280 x 1024
or 1400 x 1050 depending on the type of computer or DVI cable.
z The USB terminal is used to use the remote  control as the computer mouse. An image can-
not be projected simply by connecting the USB cable.

PROJECTING AN IMAGE FROM THE COMPUTER
Starting Projection
Connect the power cord and turn on the projector to start the projection.
1Connect the power cord.
Fully insert the power cord plug into the socket.
The [POWER] indicator flashes red.
2Remove the lens cap and press the [POWER] button.
The [POWER] indicator flashes green, and
then lights in green.
zOnce the projector is turned off, it cannot be turned on for a while. Wait until the lamp is
cooled down and the [POWER] indicator lights in red.
Caution
Connect the Ground Terminal
Connect the ground terminal on the power plug to ground. Otherwise, the operating
computer may suffer electromagnetic radiation problems and poor reception by TV and
radio.
Unplug the Power Cord When the Projector is Not in Use
The projector constantly consumes approximately 7W power even when it is turned off.
To ensure safety, malfunction prevention, and power saving, remove the power plug
from the AC outlet when the projector is not used for an extended period of time.
