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 heaters
or heat radiating appliances.
4. Exposure to direct sunlight, smoke or steam can harm in-
ternal 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.
b. The projector must be installed by qualified technicians
in order to ensure proper operation and reduce the risk
of bodily injury.
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.
Power Supply
1. The projector is designed to operate on a power supply of
100-120 or 200-240 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 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.
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
•
To replace the lamp, follow all instructions provided on page
E-33.
•
Be sure to replace the lamp when the Status light comes
on. If you continue to use the lamp after 2000 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.
•
Allow a minimum of ONE minute to elapse after turning off
the projector.Then disconnect the power cable and allow 60
minutes to cool the projector before replacing the lamp.
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.
•
•
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 look into the laser pointer while it is on and do not
point the laser beam at another person.Serious injury could
result.

Projector
This section introduces you to your new MultiSync MT840 (SVGA)/
MT1040 (XGA) Projector describes the features and controls.
Congratulations on Your Purchase of The MultiSync LMT840/
MT1040 Projector
The MultiSync MT840/MT1040 is one of the very best projectors
available today. The MultiSync MT840/MT1040 enables you to
project precise images up to 300 inches across (measured diagonally)
from your PC or Macintosh computer (desktop or notebook), VCR,
DVD player, document camera, or even a laser disc player.
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.
*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 800ן 600 crisp image with NEC technology’s Advanced AccuBlend on MT840.
*3 An SXGA image (1280
ן 1024) is converted into a 1024ן 768 crisp image with NEC technology’s Advanced AccuBlend on
MT1040.
Features you’ll enjoy:
• Simple set up and operation.
• Hot air blown from the vents does not bother the audience dur-
ing your presentation since the vents are located on the front.
• A high-performance 180 watt NSH lamp.
• The supplied wireless remote control that operates the projector
from any angle.
*4 The USB terminal meets the USB1.0 specification and accepts a
USB mouse only.
• The manual zoom control enables you to adjust the image to be
between 30 (1.3m) and 300 inches (11.2m) (measured diago-
nally).
• Keystone correction allows you to correct trapezoidal distortion
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 use the entire picture as a back-
ground image or to create slides.
• An image can be projected from in front or behind a screen, and
the projector can even be installed on the ceiling.
• NEC Technologies’ exclusive Advanced AccuBlend™ intelli-
gent pixel blending technology - an extremely accurate image
compression technology - offers a crisp image with SXGA (1280
x 1024) resolution*3 . You can select any point on the screen
with the pointer and enlarge the selected area.
• Supports most IBM VGA, SVGA, XGA*2 , SXGA(with Ad-
vanced AccuBlend)*3, Macintosh, component signal (YCbCr /
YPbPr) or any other RGB signals within a horizontal frequency
range of 15 to 85 kHz and a vertical frequency range of 50 to 85
Hz. This includes NTSC, PAL, PAL60, SECAM and NTSC4.43
standard video signals.

Press and hold the Tilt but-
ton on the left side of the
projector.
Lift the front edge of the projec-
tor to the height you want, and
release the button to lock the
Adjustable Tilt Foot.
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"
(0.76 m) measured diagonally when the projector is roughly 4 feet
(1.3 m) from the wall or screen. The largest the image can be is 300"
(7.6 m) when the projector is about 36.8 feet (11.2 m) from the wall
or screen.
To fine-tune the image’s position vertically on the screen,
rotate the foot. Each of the rear feet height can be changed
up to 0.6” (4mm).
6. If the projected image does not appear square to the screen then
use keystone correction for proper adjustment.
Using a Tabletop or Cart
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.)
7. Adjust the size of the image using the Zoom ring on the lens.

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 32˚F (0˚C)
and 104˚F (40˚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.

ConnectingYour PC or Macintosh Computer
Connecting your PC or Macintosh computer to your MultiSync
MT840 (SVGA)/MT1040 (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 Remote Control
1. Plug the supplied 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 serial cable from the mouse output port and
restart your computer to regain trackball or trackpad mouse con-
trol.
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.
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.
4. If you accidentally hit the OFF button on the remote control, wait
one full minute and then press the ON button to resume.
NOTE:The new Macintosh computer such as G3 will have the 15
pin HD connector. The MT840/MT1040's "Plug and Play" data
will be downloaded to the Macintosh. Therefore, the Mac adapter
will not be necessary.
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.

When using a Macintosh with the projector, set the DIP switches of
the supplied pin adapter according to your resolution. After setting,
restart your Macintosh.
3. Turn on the projector and the DVD player.
NOTE: Refer to your DVD player’s owner’s manual for more infor-
mation about your DVD player’s video output requirements.
See the following pages for setting of the DIP switches.
• When using with a Macintosh, SVGA(800
ן 600 :MT840)/ XGA(1024
ן 768 : MT1040) is recommended if your Macintosh supports this mode.
• When using with a Macintosh PowerBook, output may not be
set to 800
ן 600 unless “mirroring” is off on your PowerBook. Refer to owner’s manual supplied with your Macintosh com-
puter for mirroring.
Connecting Your VCR Or Laser Disc Player
Use common RCA cables (not provided) to connect your VCR or
laser disc player to your projector. To make these connections, sim-
ply:
1. Turn off the power to the projector and VCR or laser disc player.
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.
Settings for Monitor Mode
3. Turn on the projector and the VCR or laser disc player.
NOTE: Refer to your VCR or laser disc player owner’s manual for
more information about your equipment’s video output requirements.

To connect the mouse output port:
1. Turn off your computer.
2. For PCs: Remove your current mouse and connect the supplied
serial cable from the mouse output to your PC’s mouse port. (Use
the 6-pin adapter for connecting to a PS/2 computer.)
For Macintosh: Remove your current mouse from your computer,
attach the Macintosh adapter to the mouse output port’s serial cable,
and connect the projector to your mouse port.
3. When the built-in remote mouse receiver is available, it will dis-
able your regular mouse, disconnect the serial cable and restart
your computer.
NOTE: For settings other than display modes supported by your
Macintosh and the projector, use of the DIP switch may bounce an
image slightly or may display nothing. If this happens, set the DIP
switch to the 13" fixed mode and then restart your Macintosh. After
that, restore to a displayable mode and then restart the Macintosh
again. Make sure that the projector and your Macintosh are con-
nected with the pin adapter and the supplied signal cable (mini D-
Sub 15-pin connector) and then restart your Macintosh.

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.
TYPE (I, II and III)
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.
