This equipment has been tested and found to comply
with the limits for a Class B digital device, pursuant to
Part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful in-
terference in a residential installation. This equipment
generates, uses, and can radiate radio frequency en-
ergy and, if not installed and used in accordance with
the instructions, may cause harmful interference to
radio communications. However, there is no guaran-
tee that interference will not occur in a particular in-
stallation. If this equipment does cause harmful inter-
ference to radio or television reception, which can be
determined by turning the equipment off and on, the
user is encouraged to try to correct the interference
by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and
receiver.
• Connect the equipment into an outlet on a circuit dif-
ferent from that to which the receiver is connected.
• Consult the dealer or an experienced radio / TV tech-
nician for help.
In UK, a BS approved power cable with moulded plug
has a Black (five Amps) fuse installed for use with this
equipment. If a power cable is not supplied with this equip-
ment please contact your supplier.

E–2
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.
* 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 OFF button).
* While the POWER and the STATUS indicators are alternately
flashing.
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.
E–3
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.

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/

able today. The MultiSync VT440/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.
Features you’ll enjoy:

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.
• 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.
