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.  
CAUTION  
Do not unplug the power cable from the wall outlet under any  
one of the following circumstances. Doing so can cause damage  
to the projector:  
* While the Hour Glass icon appears.  
Installation  
* While the message "Please wait a little." appears. This mes-  
sage will be displayed after the projector is turned off.  
* 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 cooling  
fan continues to work for 30 seconds after the projector is  
turned off with the POWER button).  
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.  
* While the POWER and the STATUS indicators are alternately  
flashing.  
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.  
CAUTION  
Do not put the projector on its side when the lamp is turned on.  
Doing so may cause damage to the projector.  
b. The projector must be installed by qualified technicians  
in order to ensure proper operation and reduce the risk  
of bodily injury.  
CAUTION  
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.  
Avoid displaying stationary images for a prolonged period of  
time.  
Doing so can result in these images being temporarily sustained  
on the surface of the LCD panel.  
d. Please consult your dealer for more information.  
If this should happen, continue to use your projector. The static  
background from previous images will disappear.  
Power Supply  
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.  
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 message "The lamp  
has reached the end of its usable life. Please replace the  
lamp."appears.If you continue to use the lamp after the lamp  
has reached the end of its usable life, 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 30 seconds 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 (10 cm) 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.

Introduction to the MultiSync VT440/VT540 Projector  
This section introduces you to your new MultiSync VT440 (SVGA)/  
VT540 (XGA) Projector and describes the features and controls.  
Congratulations on Your Purchase of The MultiSync VT440/  
VT540 Projector  
The MultiSyncVT440/VT540 is one of the very best projectors avail-  
able today. The MultiSyncVT440/VT540 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, 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 800
ן
600 crisp  
image with NEC technology’s Advanced AccuBlend on VT440.  
*3 An SXGA image (1280
ן
1024) is converted into a 1024
ן
768  
crisp image with NEC technology’s Advanced AccuBlend on  
VT540.  
Features you’ll enjoy:  
• Simple set up and operation.  
• Front ventilation directs hot air away from your audience.  
• A high-performance 160 watt NSH (130 watt in Eco mode) lamp.  
The lamp life can be extended up to 3000 hours by using the Eco  
mode.  
• The supplied wireless remote control that operates the projector  
from any angle.  
• Manual zoom control enables you to adjust the image between  
25 (0.63 m) and 300 inches (7.6 m) (measured diagonally).  
• Keystone correction allows you to correct trapezoidal distortion  
so that the image is square.  
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 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 overview. If the section doesn’t  
apply, you can skip it.  
• You can choose between video modes depending on your source:  
“normal” for a typical picture, “natural” for true color reproduc-  
tion.  
• 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 intelligent  
pixel blending technology - an extremely accurate image com-  
pression technology - offers a crisp image with SXGA (1280 x  
1024) resolution*3.  
• 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 100 kHz and a vertical frequency range of 50 to  
117 Hz. This includes NTSC, PAL, PAL60, SECAM and  
NTSC4.43 standard video signals.  
NOTE: Composite video standards are as follows:  
NTSC: U.S. TV standard for video in U.S. and Canada.  
PAL: TV standard used in Western Europe.  
PAL60: TV standard used for NTSC playback on PAL TVs.  
SECAM: TV standard used in France and Eastern Europe.  
NTSC4.43: TV standard used in Middle East countries.

The further your projector is from the screen or wall, the larger the  
image. The minimum size the image can be is approximately 25"  
(0.64 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 39.3 feet (12.0 m) from the wall  
or screen.

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.)  
2. Connect the power cable, remove the lens cap and turn the projec-  
tor on. (If no input signal is available, the projector will display a  
background image.)  
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).

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 LM button on your remote control to correct the orientation.  
(See page E-31.)  
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 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 LM buttons on  
your remote control to correct the orientation. (See page E-31.)  
• 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.
