INSTALLATION AND CONNECTIONS
This section describes how to set up your projector and how to connect video and audio sources.
Your projector is simple to set up and use. But before you get started, you must first:
z
Set up a screen and the projector.
xConnect your video equipment to the projector. See page E-13 – 17.
cConnect the supplied power cable. See page E-17.
NOTE: Ensure that the power cable and any other cables are disconnected before moving the projector. Whenmoving the projector or when it is not in use, cover the lens with the lens cap.
Setting Up the Screen and the Projector
Selecting a Location
The further your projector is from the screen or wall, the larger the image. The minimum size the
image can be is approximately 30 (0.8 m) measured diagonally when the projector is roughly 4 feet
(1.0 m) from the wall or screen. The largest the image can be is 200 (5.08 m) when the projector is
about 23 feet (7 m) from the wall or screen. Use the drawing below as a guide.

WARNING
*Installing your projector on the ceiling must be done by a quali-
fied technician. Contact your NEC dealer for more information.
*Do not attempt to install the projector yourself.
•Only use your projector on a solid, level surface. If the projector falls
to the ground, you can be injured and the projector severely dam-
aged.
•Do not use the projector where temperatures vary greatly. The pro-
jector must be used at temperatures between 41˚F (5˚C) and 95˚F
(35˚C).
•Do not expose the projector to moisture, dust, or smoke. This will
harm the screen image.
•Ensure that you have adequate ventilation around your projector so
heat can dissipate. Do not cover the vents on the side or the front of
the projector.
Reflecting the Image
Using a mirror to reflect your projectors image enables you to enjoy a
much larger image. Contact your NEC dealer if you need a mirror. If
youre using a mirror and your image is inverted, use the MENU and
SELECT buttons on your projector cabinet or 
 buttons on your re-
mote control to correct the orientation. (See page E-33.)
NOTE: A 16:9 image is supported within the limits of the above values.

To COMPUTER IN
NOTE: An image may not be displayed correctly when a Video or S-Video source
is played back via a commercially available scan converter.
This is because the projector will process a video signal as a computer signal at
the default setting. In that case, do the following.
*When noise appears on the sides of the screen:
Use the Overscan feature to display the image correctly.
Be sure to change the Overscan to 0% before pressing the AUTO ADJ or
AUTO ADJUST button. Unless otherwise an image may be displayed with its
sides cut off.

When Viewing a DVI Digital Signal:
To project a DVI digital signal, be sure to connect the PC and the projec-
tor using a DVI-D signal cable (not supplied) before turning on your PC
or projector. Turn on the projector first and select DVI (DIGITAL) from
the source menu before turning on your PC.
Failure to do so may not activate the digital output of the graphics card
resulting in no picture being displayed. Should this happen, restart your PC.
Do not disconnect the DVI-D signal cable while the projector is running. If
the signal cable has been disconnected and then re-connected, an im-
age may not be correctly displayed. Should this happen, restar t your PC.
NOTE:
•Use the DVI-D cable compliant with DDWG (Digital Display Working Group)
DVI (Digital Visual Interface) revision 1.0 standard. The DVI-D cable should
be within 5 m (196) long.
•See page E-49 for DVI digital signals the DVI (DIGITAL) connector supports.

PROJECTING AN IMAGE (BASIC OPERATION)
This section describes how to turn on the projector and to project a
picture onto the screen.
Turning on the Projector
NOTE:
•When plugging in or unplugging the supplied power cable, make sure that the
main power switch is pushed to the off[O] position. Failure to do so may cause
damage to the projector.
•The projector has two power switches: main power switch and POWER but-
ton.
•The projector has a feature to prevent itself from being used by unauthorized
individuals. To use this feature, register your PC card as a protect key. See
Security on page E-36 for more details.
To turn on the main power to the projector, press the Main Power switch
to the ON position ( I ).
Before you turn on your projector, ensure that the computer or video
source is turned on and that your lens cap is removed.
Only after you press the POWER (ON/STAND BY) button on the projec-
tor cabinet or POWER button on the remote control for a minimum of 2
seconds will the power indicator turn to green and the projector become
ready to use.
Note on Startup screen (Menu Language Select screen)
When you first turn on the projector, you will get the Startup screen. This
screen gives you the opportunity to select one of the 18 menu languages.
1. Use the SELECT 
 or  button to select one of the 18 languages for
the menu.
3. The menu will be displayed in the language you have selected.
To close the menu, press the CANCEL button.
After this has been done, you can proceed to the menu operation.
If you want, you can select the menu language later. See Language
on page E-33.
When the Lamp mode is set to Eco, the Lamp indicator will light green.
If one of the following things happens, the projector will not turn on.
*If the internal temperature of the projector is too high, the projector
detects abnormal high temperature. In this condition the projector
will not turn on to protect the internal system. If this happens, wait for
the projectors internal components to cool down.
*When the lamp reaches its end of usable life, the projector will not
turn on. If this happens, replace the lamp.
*If the lamp fails to light, and if the STATUS indicator flashes on and
off in a cycle of six times, wait a full minute and then turn on the
power.
