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
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 techni-
cians in order to ensure proper operation and reduce
the risk of bodily injury.
c. In addition, the ceiling must be strong enough to sup-
port 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
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.
CAUTION
Do not turn off the main power or unplug the power cable
from the wall outlet under any one of the following circumstances. Doing so can cause damage to the projector:
• Immediately after the power cable is plugged into the wall
outlet (when the POWER indicator has not changed to a
steady orange glow).
• Immediately after the cooling fan stops working (The cooling fan continues to work for 60 seconds after the projector is turned off with the POWER button).
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.
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-36.
• 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 60 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 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 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 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.

1. INTRODUCTION
Introduction to the VT45 Projector
This section introduces you to your new VT45 (SVGA) Projector and describes the features and controls.
Congratulations on Your Purchase of The VT45 Projector
The VT45 is one of the very best projectors available today. The
VT45 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
projector to project images from behind the screen, and the projector can be permanently mounted on a ceiling*
control can be used wirelessly.
Features you’ll enjoy:
• Simple set up and operation.
• Eco Mode, two selectable options (120 watt for Eco 1 and
110 watt for Eco 2) that allow users to reduce the projector’s
light output, resulting in a doubling (Eco 2) of usable lamp
life and decreased lamp replacement costs throughout the
projector’s life.
• A high-performance 130 watt NSH lamp.
• Manual horizontal (max 1/3 of widith) and vertical (max 1/
2 of height) lens shift provides simple imaging positioning.
• The lamp life can be extended up to 2000 hours by using
the Eco 2 mode.
• The supplied wireless remote control that operates the projector from the front side or rear.
• 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.
• Color Management feature includes Gamma Correction,
White Balance, and Color Correction that provides natural
and true color reproduction.
• You can choose between video modes depending on your
source: “normal” for a typical picture, “natural” for true
color reproduction.
• 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 1024) resolution*
• Supports most IBM VGA, SVGA, XGA*
Macintosh, component signal (YCbCr / YPbPr) or any other
RGB signals within a horizontal frequency range of 15 to
80 kHz and a vertical frequency range of 50 to 100 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 Con-
trol port.
• The contemporary cabinet design is light, compact, easy to
carry, and complements any office, boardroom or auditorium.
*1 Do not attempt to mount the projector on a ceiling your-
self. 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 (1024768) and SXGA image
(12801024) are converted into an 800600 crisp image
with NEC technology’s Advanced AccuBlend.
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.
