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.  
You can use the projector on a tabletop or cart, you can use the pro-  
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.  
*2 An XGA image (1024
ן
768) is converted into an 800
ן
600 crisp  
image with NEC’s Advanced AccuBlend on LT84.  
*3 An SXGA image (1280
ן

so that the image is square.  
You can choose between video modes depending on your source:  
“normal” for a typical picture, “natural” for true color reproduc-  
tion.  
Getting Started  
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.

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 in the supplied  
soft carrying case.  
You must put the projector in the soft carrying case with  
the lens upward as shown below. This is to prevent the  
lens from damage.  
5. To center the image vertically, lift the front edge of the projector  
and press the One-Push Tilt buttons on the front side of the pro-  
jector, just above the feet, to release the Front Adjustable feet.

6. If necessary, adjust the front or rear feet to properly position the  
projected image on the screen.  
If the projected image does not appear square to the screen then  
use keystone correction for proper adjustment. The Lever-Type  
Adjustable Rear foot height can be changed up to 3 degrees.  
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 25"  
(0.6 m) measured diagonally when the projector is roughly 4 feet  
(1.2 m) from the wall or screen. The largest the image can be is 300"  
(7.6 m) when the projector is about 40 feet (12.2 m) from the wall or  
screen.

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.

To mini D-Sub 15-pin connector on the projector. It is recommended that  
you use a commercially available distribution amplifier if connecting a  
signal cable longer than the supplied one.  
ConnectingYour PC or Macintosh Computer  
Connecting your PC or Macintosh computer to your MultiSync LT84  
(SVGA)/LT140 (XGA) projector will enable you to project your  
computer’s screen image for an impressive presentation.  
To connect to a PC or Macintosh, simply:  
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.

2. Connect one end of your RCA cable to the video output connector  
on the back of your VCR or laser disc player, connect the other  
end to theVideo input on your projector. Use standard RCA audio  
patch cords to connect the audio from your VCR or laser disc  
player to the projector (if your VCR or laser disc player has this  
capability). Be careful to keep your right and left channel connec-  
tions correct for stereo sound.  
NOTE: A Video Adapter cable manufactured by Apple Computer is  
needed for a PowerBook which does not have a mini D-Sub 15-pin  
connector.

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.
