Cleaning
1. Unplug the projector before cleaning.
2. Clean the cabinet periodically with a damp cloth. If
heavily soiled, use a mild detergent. Never use strong
detergents or solvents such as alcohol or thinner.
3. Use a blower or lens paper to clean the lens, and be careful
not to scratch or mar the lens.
Lamp Replacement
• Perform lamp replacement in accordance with the in-
structions on page E-37.
• Be sure to replace the lamp when the Status light comes
on. If you continue to use the lamp after 1000 hours of
use, the lamp bulb may shatter, and pieces of glass may
be scattered in the lamp case. Do not touch them as the
pieces of glass may cause injury. If this happens, contact
your NEC dealer for lamp replacement.
• Allow a minimum of ONE minute to elapse between
turning the lamp off and on. High voltage is applied to the
lamp immediately when the power is turned on. There-
fore turning the power off and quickly back on may
shorten the life of your lamp and result in damage to your
projector.
Fire and Shock Precautions
1. Ensure that there is sufficient ventilation and that vents
are unobstructed to prevent the build-up of heat inside
your projector. Allow at least 10cm of space between your
projector and a wall.
2. Prevent foreign objects such as paper clips and bits of
paper from falling into your projector. Do not attempt to
retrieve any objects that might fall into your projector. Do
not insert any metal objects such as a wire or screwdriver
into your project. If something should fall into your
projector, disconnect it immediately and have the object
removed by a qualified NEC service person.
3. Do not place any liquids on top of your projector.
• Do not look into the lens while the projector is on.
Serious damage to your eyes could result.
• Do not look into the laser pointer while it is on and do
not point the laser beam at another person. Serious
injury could result.
Important Safeguards
These safety instructions are to ensure the long life of your
projector and to prevent fire and shock. Please read them
carefully and heed all warnings.
Installation
1. For best results, use your projector in a darkened room.
2. Place the projector on a flat, level surface in a dry area
away from dust and moisture.
3. Do not place your projector in direct sunlight, near heat-
ers or heat radiating appliances.
4. Exposure to direct sunlight, smoke or steam can harm
internal components.
5. Handle your projector carefully. Dropping or jarring can
damage internal components.
6. Do not place heavy objects on top of the projector.
7. If installing the projector on the ceiling:
a. The ceiling must be strong enough to support the
projector and the installation must be in accordance
with any local building codes.
b. The projector must be installed by qualified NEC
service personnel.
Power Supply
1. The projector is designed to operate on a power supply of
100-120 or 220-240 V 50/60 Hz AC. Ensure that your
power supply fits this requirement before attempting to
use your projector.
2. Handle the power cable carefully and avoid excessive
bending. A damaged cord can cause electric shock or fire.
3. If the projector is not to be used for an extended period of
time, disconnect the plug from the power outlet.

This section describes how to set up your MultiSync LT100
projector and how to connect video and audio sources.
Setting Up Your MultiSync LT100
Projector
Your MultiSync LT100 Projector is simple to set up and use.
But before you get started, you must first:
1. Determine the image size
2. Set up a screen or select a non-glossy white wall onto
which you can project your image.
Carrying The Projector Always carry your projector by the
handle. Ensure that the power cord and any other cables
connecting to video sources are disconnected before mov-
ing the projector. When moving the projector or when it is
not in use, cover the lens with the lens cap.
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 24" (0.61 m) measured
diagonally when the projector is roughly 1.2 m from the
wall or screen. The largest the image can be is 300" (7.6 m)
when the projector is about 12.3 m from the wall or screen.

1. Place your projector on a flat level surface at the optimal
distance from the screen or wall so you realize the size
image you want. (Avoid having bright room lighting or
sun light directly on the screen or wall where you'll be
projecting the image.)
2. Connect the power cable, remove the lens cap and turn the
projector on. (If no input signal is available, the projector
will display a background image.)
3. Ensure that the projector is square to the screen.
4. Move the projector left or right to center the image
horizontally on the screen. (A)
5. To center the image vertically (B), lift the front edge of the
projector and press the buttons on the front of the projec-
tor, just above the feet, to release the one-touch tilt feet.
(There is approximately 5.0˚ of up and down adjustment
for the front of the projector.
6. To fine tune the image's position vertically on the screen,
rotate each front foot, and rear feet if necessory.
Note: Adjust feet so that lens surface is parallel to the screen. If
you use the projector with the screen tilted, the picture will be
distorted.
7. Adjust the size of the image using the zoom ring lever on
the lens.
Note: The set up angle of the projector should not exceed 15
degrees, otherwise lamp life could decrease dramatically.

When storing the remote control, place the remote in its protective case. The
case will keep the remote buttons from being accidentally pushed while it is
being stored or transported. This will keep the batteries from being dis-
charged.
4. Zip up the top of the case.
* Carry the projector carefully. Bumping or dropping the
projector may cause damage.

WARNING
• Only use your projector on a solid, level surface. If the
projector falls to the ground, you can be injured and the
projector severely damaged.
• Do not use the projector where temperatures vary greatly.
The projector must be used at temperatures between 5˚C
and 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 bottom or the side of the projector.
Ceiling Installation
Installing your MultiSync LT100 Projector on the ceiling
must be done by a qualified technician. Contact your NEC
dealer for more information.
Do not attempt to install the projector yourself.
Note: Distances may vary ±5%.
If your projector is mounted on the ceiling and your image is
upside down, use the “Menu” and “Select” buttons on your
projector cabinet or (▲) (▼) buttons on your remote control
to correct the orientation. (See page 68.)

Remote Control Guideline
1. Plug the serial cable with the remote mouse receiver into your computer's mouse port and restart your computer to gain
remote mouse control.
2. When using the remote control's built-in infrared mouse on a laptop computer, the laptop's mouse, trackball or trackpad will
be disabled. Disconnect the infrared receiver and restart your computer to regain trackball or trackpad mouse control.
3. If the screen goes blank while using your remote control, it may be the result of the computer's screen-saver or power
management software. If you accidentally hit the OFF button on the remote control, wait one full minute and then press the
ON button to resume.

Connecting Your PC Or Macintosh
Computer
Connecting your PC or Macintosh computer to your
MultiSync LT100 (XGA) Projector will enable you to project
your computer's screen image for an impressive presentation.
All of these following display standards are supported:
To connect to a PC, Macintosh or computer equipped with an
XGA/SVGA/VGA adapter or compatible graphics adapter,
simply:
1. Turn off the power to your projector and computer.
2. If your PC does not support XGA/SVGA/VGA you will
need to install an XGA/SVGA/VGA graphics board.
Consult your computer's owner's manual for your XGA/
SVGA/VGA configuration. If you need to install a new
board, see the manual that comes with your new graphics
board for installation instructions.
3. Use the signal cable that's supplied to connect your PC or
Macintosh computer to the projector. For Macintosh, use
the supplied pin adapter to connect to your computer's
video port.
4. Turn on the projector and the computer.
5. If the projector goes blank after a period of inactivity, it
may be caused by a screen saver installed on the com-
puter you've connected to the projector.
