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.
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.
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.
Lamp Replacement
•
To replace the lamp, follow all instructions provided on page
E-33.
3. Do not place your projector in direct sunlight, near heaters
or heat radiating appliances.
•
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 scat-
tered 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.
4. Exposure to direct sunlight, smoke or steam can harm inter-
nal components.
5. Handle your projector carefully.Dropping or jarring can dam-
age internal components.
6. Do not place heavy objects on top of the projector.
7. If you wish to have the projector installed on the ceiling:
a. Do not attempt to install the projector yourself.
•
Allow a minimum of ONE minute to elapse between turning
the lamp off and on.
b. The projector must be installed by qualified technicians
in order to ensure proper operation and reduce the risk
of bodily injury.
High voltage is applied to the lamp immediately when the
power is turned on.
Therefore turning the power off and quickly back on may
shorten the life of your lamp and result in damage to your
projector.
c. In addition, the ceiling must be strong enough to support
the projector and the installation must be in accordance
with any local building codes.
d. Please consult your dealer for more information.
CAUTION
Power Supply
Do not unplug the power cable from the wall outlet under any one of
the following circumstances. Doing so can cause damage to the pro-
jector:
1. The projector is designed to operate on a power supply of
100-120 or 200-240V 50/60 Hz AC. Ensure that your power
supply fits this requirement before attempting to use your
projector.
*
*
While the Hour Glass icon appears.
While the message "Please wait a little." appears.This mes-
sage will be displayed after the projector is turned off.
2. Handle the power cable carefully and avoid excessive bend-
ing. 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.
*
*
*
Immediately after the power cable is plugged into the wall
outlet (the POWER indicator has not changed to a steady
amber glow).
Immediately after the cooling fan stops working (The cool-
ing fan continues to work for ONE minute after the projector
is turned off with the POWER OFF button).
While the POWER and the STATUS indicators are alternately
flashing.
E–3
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 pro-
jector.Allow at least 3 inches (10cm) of space between your
projector and a wall.
2. Prevent foreign objects such as paper clips and bits of pa-
per from falling into your projector. Do not attempt to re-
trieve any objects that might fall into your projector. Do not
insert any metal objects such as a wire or screwdriver into
your projector. If something should fall into your projector,
disconnect it immediately and have the object removed by a
qualified NEC service personnel.
3. Do not place any liquids on top of your projector.
Warnings
•
Do not look into the lens while the projector is on. Serious
damage to your eyes could result.
•
Keep any items such as magnifying glass out of the light
path of the projector.The light being projected from the lens
is extensive, therefore any kind of abnormal objects that
can redirect light coming out of the lens, can cause unpre-
dictable outcome such as fire or injury to the eyes.
•
•
Do not cover the lens with the supplied lens cap or equiva-
lent while the projector is on. Doing so can lead to melting of
the cap and possibly burning your hands due to the heat
emitted from the light output.
Do not hold the lens part. Doing so may cause the risk of
injury.
For the optional full function remote control with
the laser pointer
•
Do not look into the laser pointer while it is on and do
not point the laser beam at another person. Serious in-
jury could result.

and you can even use the optional full function remote control
and mouse adapter to operate your PC or Macintosh mouse
wirelessly from across the room with the built-in remote mouse
receiver.
Projector
This section introduces you to your new MultiSync LT84 (SVGA)/
LT140 (XGA) Projector describes the features and controls.
Congratulations On Your Purchase Of The MultiSync LT84/
LT140 Projector
• You can control the projector with a PC using the PC Control
port.
The MultiSync LT84/LT140 is one of the very best projectors avail-
able today. The MultiSync LT84/LT140 enables you to project pre-
cise images up to 300 inches across (measured diagonally) from your
PC or Macintosh computer (desktop or notebook),VCR, DVD player,
document camera, a laser disc player, or PC Card Viewer.

jector to project images from behind the screen, and the projector can
be permanently mounted on a ceiling*1. The remote control can be
used wirelessly.
• The contemporary cabinet design is light, compact, easy to carry,
and complements any office, boardroom or auditorium.
• Eight kinds of pointers are available for your presentation.
• USB terminal allows USB mouse operation*4.
*1 Do not attempt to mount the projector on a ceiling yourself.
The projector must be installed by qualified technicians in order
to ensure proper operation and reduce the risk of bodily injury.
In addition, the ceiling must be strong enough to support the pro-
jector and the installation must be in accordance with any local
building codes. Please consult your dealer for more information.

ing your presentation since the vents are located on the front and
bottom.
• A high-performance AC120 watt P-VIP lamp.
• A wireless card remote control that can be stored in the projec-
tor.
• The manual zoom control enables you to adjust the image to be
between 25 and 300 inches (measured diagonally).

The fastest way to get started is to take your time and do everything
right the first time. Take a few minutes now to click through the CD-
ROM and review the user’s manual. This may save you time later on.
At the beginning of each section of the manual you’ll find an over-
view. If the section doesn’t apply, you can skip it.
• The built-in PC Card Viewer allows you to start your presenta-
tion even when a PC is not available at the site.
• The “Capture” enables you to capture the current projected im-
age.
• An image can be projected from in front or behind a screen, and

If your projector is mounted on the ceiling and your image is upside
down, use the “Menu” and “Select” buttons on your projector cabi-
net or ▲▼ button on your remote control to correct the orientation.
(See page E-23.)
WARNING
• Installing your projector on the ceiling must be done by a quali-
fied technician. Contact your NEC dealer for more informa-
tion.
* Do not attempt to install the projector yourself.
• Only use your projector on a solid, level surface. If the projec-
tor 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 41˚F (5˚C)
and 95˚F (35˚C).
Reflecting the Image
Using a mirror to reflect your projector’s image enables you to enjoy
a much larger image. Contact your NEC dealer if you need a mirror.
If you’re using a mirror and your image is inverted, use the “Menu”
and “Select” buttons on your projector cabinet or ▲▼ buttons on
your remote control to correct the orientation. (See page E-23.)
• Do not expose the projector to moisture, dust, or smoke. This
will harm the screen image.
• Ensure that you have adequate ventilation around your pro-
jector so heat can dissipate. Do not cover the vents on the side
or the front of the projector.

Remote Control Guideline for the Optional Full Func-
tion Remote Control
1. Plug the optional serial cable with the mouse output port of the
projector into your computer’s mouse port and restart your com-
puter 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 dis-
abled. Disconnect the optional serial cable from the mouse output
port 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 manage-
ment software.
1. Turn off the power to your projector and computer.
2. Use the signal cable that’s supplied to connect your PC or
Macintosh computer to the projector. For older Macintosh, use
the supplied pin adapter to connect to your Mac's video port.
NOTE:The new Macintosh computer such as G3 will have the 15
pin HD connector. The LT84/LT140's "Plug and Play" data will
be downloaded to the Macintosh. Therefore, the Mac adapter will
not be necessary.
4. If you accidentally hit the OFF button on the remote control, wait
one full minute and then press the ON button to resume.
3. Turn on the projector and the computer.
4. If the projector goes blank after a period of inactivity, it may be
caused by a screen saver installed on the computer you’ve con-
nected to the projector.

Terminology
PC card
This is the name of a card currently being standardized by the Japan Electronic Industry Association (JEIDA) and
PCMCIA (Personal Computer Memory Card Interface Association) of the United States.
ATA card
A type of PC card. ATA was originally a type of interface between computers and fixed disk devices. The ATA card
is a standard card-type recording medium.
CompactFlash
TYPE (I, II and III)
CompactFlash card is a small removable card conforming to ATA specifications. It is one-fourth the volume of a
PCMCIA card.
PCMCIA 2.1 PC cards are divided into three types according to their thickness: Type I (3.3 mm), Type II (5.0 mm)
and Type III (10.5 mm).
BMP
JPEG
A type of image format. The standard Windows Bit Map format used for MS-DOS/Windows-compatible comput-
ers.
A type of image format. "JPEG" is the abbreviation of Joint Photographic Experts Group. JPEG compression offers
efficient data storage. The data not required for displaying the image is identified and deleted. Since the data is
deleted, JPEG algorithms are said to be irreversible. This means that once the image is compressed, the decom-
pressed image it is not the same as the original image.

4. MAINTENANCE
This section describes the simple maintenance procedures you should
follow to replace the lamp, and replace the coin cell in the remote
control.
4. Insert a new lamp housing until the lamp housing is plugged into
the socket.
Replacing The Lamp
After your lamp has been operating for 1000 hours or longer, the
“Status” light in the cabinet will go on. Even though the lamp may
still be working, replace it at 1000 hours to maintain optimal projec-
tor performance.
5. Secure it in place with the three screws.
Be sure to tighten the three screws.
CAUTION
• DO NOT TOUCH THE LAMP immediately after it has been
used. It will be extremely hot. Turn off the power to the pro-
jector and allow at least one hour for the lamp to cool. Then
disconnect the power cable.
• DO NOT REMOVE ANY SCREWS except the lamp cover
screw and three lamp case screws. You could receive an elec-
tric shock.
• The projector will turn off and go into stand by mode after
1100 hours of service. If this happens, be sure to replace the
lamp. If you continue to use the lamp after 1000 hours of use,
the lamp bulb may shatter, and pieces of glass may be scat-
tered 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.
CAUTION: Do not use a lamp other than the NEC replace-
ment lamp (LT40LP).
Order this from your NEC dealer.
6. Reattach the lamp cover.
To replace the lamp:
1. Loosen the lamp cover screw until the screwdriver goes into a free-
wheeling condition and remove the lamp cover. The lamp cover
screw is not removable.
7. Tighten the lamp cover screw.
2. Loosen the three screws securing the lamp housing until the screw-
driver goes into a freewheeling condition. The three screws are
not removable.
Be sure to tighten the lamp cover screw.
3. Remove the lamp housing by pulling out the handle.
8. After you install a new lamp, select [Main Menu] → [Projector
Options] → [Setup]→[Page 2]→[Clear Lamp Hour Meter] to re-
set the lamp usage hours.
NOTE: When the lamp exceeds 1100 hours of service, the projector
cannot turn on and the menu is not displayed. If this happens, press
the Help button on the remote control for a minimum of 10 seconds
while in standby mode. When the lamp time clock is reset to zero, the
STATUS indicator goes out.
NOTE: There is an interlock on this case to prevent the risk of elec-
trical shock. Do not attempt to circumvent this interlock.
