INSTALLING THE PROJECTOR
Determining the Installation Place
Placing in Front of the Screen
Place the projector in front of the screen in such a manner that it is as perpendicular to the
screen as possible.
A slight error in the projection angle can be corrected using the KEYSTONE
button. (P31)
Placing on a Level Place
Place the projector on a level place.
• Make sure that the installation place is free from any obstacle that may block the
exhaust vent (fan) on the right side of the projector and the air intake vent (air
filter) on the bottom of the projector.
• The 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.
Note
This projector can be hung from the ceiling (Ceiling mounted) with it turned up side down.
When a translucent screen is used, the projector can project an image from behind the
screen (Rear). 
When the projector is hung from the ceiling or projector projects an image from behind the
screen, the image must be inverted vertically or horizontally. (P61)
When hanging the projector from the ceiling, optional brackets (part No. RS-CL01)
are required.

INSTALLING THE PROJECTOR
 Adjusting the Projection Angle
The projection angle can be adjusted with the adjustable foot.
Before making this adjustment, connect the computer and AV equipment and project an
image on the screen.
With the adjustable foot, the projection angle can be adjusted up to 10 degrees.
Adjust the longitudinal tilt of the projector to +/-20 degrees or less. If the tilt is more
than 20 degrees above and below, a lamp problem can result.
If Keystone Distortion is Large
Extending the adjustable foot too far causes keystone distortion (the projected picture is
trapezoidal). If the distortion is large, adjust the height of the pedestal of the projector.
The keystone distortion can be corrected using the KEYSTONE button. (P31)

PROJECTING AN IMAGE FROM THE COMPUTER
Connecting the Projector to the Computer
Connect the projector to the computer.
Connecting to Video Terminals
•Before connecting cables, turn off both the projector and computer.
• Images may be improperly projected with digital RGB signals in 1280 x 1024 or 1400 x
1050 depending on the type of computer or DVI cable.
• The USB terminal is used to use the remote control just like the computer mouse. Images
cannot be projected simply by connecting the USB cable.
To ensure projection of high-resolution high-quality images, use of high-performance cables
is recommended.
MAC Adapter (part No. LV-AD02)
For the Macintosh having a D-sub 15-pin (standard) terminal for monitor output, use a MAC adapter.
Set the slide switches (1-6) on the adapter depending on the Macintosh mode as shown below.

Connecting to Audio Terminals
Before connecting cables, turn off both the projector and computer.
Connect audio cables as required.
• Use an audio cable without a built-in resistor. Using an audio cable with a built-in
resistor turns down the sound.
• The built-in speaker is monaural.
• The speaker plays the sound from the equipment which the audio cable is
connected to.
Projecting the Image from the Notebook Computer
No image is projected if the external monitor output is turned off on the personal computer
side. 
To turn on the external monitor output, press the [LCD] or [VGA] function key while
pressing the Fn key on the keyboard of the personal computer.
The following table shows relationships between personal computer manufacturers and
key combinations.
For the key combination of the computer series not listed in the above table, refer
to the User’s Manual that came with the computer.

Determining the Output Resolution of the Computer
To make the most of the display performance of this projector, set output signal resolution
of the computer to an optimum value. If the resolution set on the computer is low, the
quality of the projected image is poor.
The procedure for adjusting the resolution is as follows:
Windows XP
1. Open the [Start] menu and select
Control Panel. 
2.
In the Control Panel window,
double-click the [Display] icon to display
the Display Properties window.
3. Select the [Settings] tab and move the
slider to select “1400 by 1050 pixels”. If
this resolution is not available, select
the highest resolution under 1400 by
1050.
4. Click the [OK] button.
Macintosh OSX
1. Open the Apple Menu and select
[System Environment Setting].
2. In the System Environment Setting
window, click the [Displays] icon to
display the Display window.
3. Select the [Display] tab and select
“1400 x 1050” from the [Resolution] list.
If this setting is not available, select the
highest resolution under 1400 x 1050.
4. Close the windows.
• Select a screen mode according to the aspect ratio corresponding to the selected
resolution (4:3 for 1400 by 1050 dots). (P33)
• If the display resolution of the computer is set to SXGA (1280 by 1024 dots) or
WXGA (1360 by 768 dots), select [True size] as the screen mode.

Caution
Connect the ground terminal of the power plug to the ground level in order to
use the projector safely. Otherwise, the operating computer may cause
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 about 6W power even when the Power
button is turned off. To ensure safety and power saving, remove the power plug
from the AC outlet when the projector is not used for an extended period of
time.
Turning On the Projector
Once the projector is turned off, it cannot be turned on for about 60 seconds. Wait
until the lamp cooling period ends and the [POWER] indicator lights red.

PROJECTING AN IMAGE FROM THE COMPUTER
Using the Auto PC Adjustment Function
This projector automatically selects a signal type (VGA, SVGA, XGA, SXGA, SXGA+,
etc.) and makes optimum settings for the total number of dots and tracking depending on
the connected computer (auto PC adjustment). (This function cannot be used when digital
RGB is selected.)
When you switched to the computer mode using the [COMPUTER-1] or [COMPUTER-2]
button, press the [AUTO PC] button. The auto PC adjustment becomes active to display
images correctly.
For some computers, the auto PC adjustment does not work. In this case, you
need to make settings (total dots, tracking, horizontal/vertical positions, horizontal/
vertical pixels, etc.) for the input signal.
• The last used signal types are recorded for the [COMPUTER-1] and
[COMPUTER-2] buttons respectively. When the projector is connected to the
same computer, it can be used with the same settings as before simply by
switching to the computer mode.
• For the settings for the input signal, refer to P52 to 57.
