Important Safeguards

These safety instructions are to ensure the long life of
your projector and to prev ent 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 in­ternal components.

5. Handle your projector carefully . Dropping or jarring can dam­age 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 A C. Ensure that y our power
supply fits this requirement before attempting to use your
projector.

2. Handle the pow er cable carefully and a void e xcessive bend­ing. 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.

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 button).

* While the POWER and the ST ATUS indicators are alternately

flashing.

CAUTION

Do not put the projector on its side when the lamp is turned on.
Doing so may cause damage to the projector.

CAUTION

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.
If this should happen, continue to use your projector. The static
background from previous images will disappear.

E–4

Lamp Replacement

• T o replace the lamp , f ollow 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 allo w 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 y our pro­jector. 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 pa­per from falling into your projector. Do not attempt to re­trieve 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 remov ed 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 unpre­dictable outcome such as fire or injury to the eyes.

• Do not cover the lens with the supplied lens cap or equiva­lent 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 (SV GA)/
VT540 (XGA) Projector and describes the features and controls.

Congratulations on Your Purchase of The MultiSync VT440/
VT540 Projector

The MultiSync VT440/VT540 is one of the very best projectors a vail­able today. The MultiSync VT440/VT540 enables you to project pre­cise images up to 300 inches across (measured diagonally) from your
PC or Macintosh computer (desktop or notebook), VCR, D VD player,
document camera, or even a laser disc player.
You can use the projector on a tabletop or cart, you can use the pro­jector 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:

• 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.

• Y ou 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 com­pression 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 supplied remote control can be used without a cable.

• You can control the projector with a PC using the PC Control

port.

• The contemporary cabinet design is light, compact, easy to carry,
and complements any office, boardroom or auditorium.

• Eight pointers are available for your presentation.

*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 pro­jector and the installation must be in accordance with any local
building codes. Please consult your dealer for more information.

*2 An XGA image (1024768) is conv erted into an 800600 crisp

image with NEC technology’s Adv anced AccuBlend on VT440.

*3 An SXGA image (12801024) is converted into a 1024768

crisp image with NEC technology’s Advanced AccuBlend on

2. INSTALLATION

This section describes how to set up your MultiSync VT440/VT540
projector and how to connect video and audio sources.

Setting up Y our Projector

Y our MultiSync VT440/VT540 Projector is simple to set up and use.
But before you get started, you must first:

1. Determine the image size.

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 by the handle.
Ensure that the power cable and any other cables connecting to video
sources are disconnected before moving the projector.

When moving the projector or when it is not in use, cover the lens

with the lens cap.

Using a T abletop 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 projec­tor on. (If no input signal is available, the projector will display a
background image.)

3. Ensure that the projector is square to the screen.

4. Move the projector left or right to center the image horizontally
on the screen.

5. To center the image vertically, lift the front edge of the projector
and press the One-Touch Tilt button on the front side of the pro­jector to release the Front Adjustable foot.

(There is approximately 10 degrees of up and down adjustment
for the front of the projector.)

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"
(0.64 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.

WARNING

• Installing your projector on the ceiling must be done by a quali­fied technician. Contact your NEC dealer for more informa­tion.

* Do not attempt to install the projector yourself.

• Only use your projector on a solid, level surface. If the projec­tor 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).

• Do not expose the projector to moisture, dust, or smoke. This
will harm the screen image.

• Ensure that you have adequate ventilation around your pro­jector so heat can dissipate. Do not cover the vents on the side
or the front of the projector.

If your projector is mounted on the ceiling and your image is upside
down, use the “Menu” and “Select” buttons on your projector cabi­net or ▲▼ button on your remote control to correct the orientation.
(See page E-31.)

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-31.)

4. MAINTENANCE

This section describes the simple maintenance procedures you should
follow to replace the lamp, clean the filter, and replace the batteries
in the remote control.

Replacing the Lamp

After your lamp has been operating for 2000 hours (up to 3000 hours
in Eco mode) or longer, the “Status” light in the cabinet will go on
and the message will appear. Even though the lamp may still be work­ing, replace it at 2000 (up to 3000 hours in Eco mode) hours to main­tain optimal projector performance.

CAUTION

• DO NOT T OUCH THE LAMP immediately after it has been
used. It will be extremely hot. Turn the projector off, wait 30
seconds, and then disconnect the power cable. Allow at least
one hour for the lamp to cool before handling.

• DO NOT REMOVE ANY SCREWS except the lamp cover
screw and two lamp case screws. Y ou could receive an electric
shock.

•

The projector will turn off and go into stand by mode after 2100
(up to 3150 hours in Eco mode) hours of service. If this happens,
be sure to replace the lamp. If you continue to use the lamp after
2000 hours (up to 3150 hours in Eco mode) of use, 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.

To replace the lamp:

1. Loosen the lamp cover screw until the screwdriver goes into a
freewheeling condition and remove the lamp co ver. The lamp cover
screw is not removable.

Cleaning or Replacing the Filters

The air-filter sponge keeps the inside of the MultiSync VT440/VT540
Projector free from dust or dirt and should be cleaned after every 100
hours of operation (more often in dusty conditions). If the filter is
dirty or clogged, your projector may overheat.

CAUTION

• Tur n off the power and unplug the projector before re­placing the filter.

• Only clean the outside of the filter cover with a vacuum
cleaner.

• Do not attempt to operate the projector without a filter
cover.

• Your projector will not operate unless the filter cover is
installed correctly.
