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 (1024768) and SXGA image

(12801024) are converted into an 800600 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.

2. INSTALLATION

This section describes how to set up your VT45 projector and
how to connect video and audio sources.

Setting up Your Projector

Your VT45 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.

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.

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
3 feet (1.0 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
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.

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 ▲▼ buttons on your remote control to correct
the orientation. (See page E-33.)

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-33.)

4. MAINTENANCE

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

Replacing the Lamp

After your lamp has been operating for 1000 hours (up to 2000
hours in Eco 2 mode and up to 1500 hours in Eco 1 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 1000 (up to 2000 hours in Eco 2 mode and up to
1500 hours in Eco 1 mode) hours to maintain optimal projector
performance.

CAUTION

•

DO NOT TOUCH THE LAMP immediately after it has been
used. It will be extremely hot. Turn the projector off, wait
60 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. You could re­ceive an electric shock.
The projector will turn off and go into stand by mode after

•

1100 (up to 2100 hours in Eco 2 mode and up to 1600 hours
in Eco 1 mode) hours of service. If this happens, be sure to
replace the lamp. If you continue to use the lamp after 1100
hours (up to 2100 hours in Eco 2 mode and up to 1600 hours
in Eco 1 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 cover. The
lamp cover screw is not removable.

2. Loosen the two screws securing the lamp housing until the
screwdriver goes into a freewheeling condition. The two
screws are not removable.

Remove the lamp housing by pulling out the handle.

NOTE: There is an interlock on this case to prevent the risk
of electrical shock. Do not attempt to circumvent this inter­lock.

Interlock

3. Insert a new lamp housing until the lamp housing is plugged
into the socket.

CAUTION

Do not use a lamp other than the NEC replacement lamp
(VT45LP).
Order this from your NEC dealer.

Secure it in place with the two screws.

Be sure to tighten the screws.

4. Reattach the lamp cover.

Tighten the lamp cover screw.

Be sure to tighten the screw.

E–36

5. After you install a new lamp, select [Advanced Menu] →
[Projector Options]→[Setup]→[Page 4]→[Clear Lamp Hour
Meter] to reset the lamp usage hours.

NOTE: When the lamp exceeds 1100 hours (up to 2100 hours in
Eco 2 mode and up to 1600 hours in Eco 1 mode) of service, the
projector cannot turn on and the menu is not displayed. If this
happens, press the Help button on the remote control for a mini­mum of 10 seconds while in standby mode. When the lamp time
clock is reset to zero, the STATUS indicator goes out.

Cleaning or Replacing the Filters

The air-filter sponge keeps the inside of the VT45 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

• Turn 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.

To clean the air-filter:
When “Clean Filter” option is turned on, the “Please clean the
filters” message will be displayed each time the projector is turned
on after it has been used in excess of 100 hours. Should this
message appear, clean the filters.

• The message can be turned on or off using the “Menu” - “Fil­ter Clean Message” option on the Setup menu. See page E-

33.

• After cleaning the filters and resetting the filter usage time
back to zero, the message will not be displayed.
See page E-35 for resetting the filter usage time.

Vacuum the filter-through the filter cover.

2. Reinstall the new filter cover.

NOTE: Do not detach the sponge from the filter cover. Do not
wash the filter cover with soap and water. Soap and water will
damage the the filter membrane. Before replacing the filter cover,
remove dust and dirt from the projector cabinet. Keep out dust
and during filter replacement.

NOTE: When you replace the lamp, it is also wise to replace the
filters. The filters come in the same package with your replace­ment lamp.

NOTE: A mix-up between the two filter covers can cause a dam­age to the projector.
The front and the side filter covers appear to be the same shape,
but they are not interchangeable with each other.
