Warnings

• 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.

• Do not hold the lens part. Doing so may cause the risk of
injuly.

• Hot air blown from the vents does not bother the audience dur­ing your presentation since the vents are located on the front and
bottom.

• A high-performance AC120 watt P-VIP lamp.

• A wireless card remote control that can be stored in the projec­tor.

• The manual zoom control enables you to adjust the image to be
between 25 and 300 inches (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 reproduc­tion.

• The built-in PC Card Viewer allows you to start your presenta­tion even when a PC is not available at the site.

• The “Capture” enables you to capture rhe current projected im­age.

• An image can be projected from in front or behind a screen, and
the projector can even be installed on the ceiling.

• NEC’s exclusive Advanced AccuBlend intelligent pixel blend­ing technology - an extremely accurate image compression tech­nology - offers a crisp image with SXGA (128021024) resolu­tion*3 . You can select any point on the screen with the pointer
and enlarge the selected area.

• Supports most IBM VGA, SVGA, XGA*2 , SXGA(with Ad­vanced AccuBlend)*3, Macintosh, component signal (YCbCr /
YPbPr) or any other RGB signals within a horizontal frequency
range of 15 to 85 kHz and a vertical frequency range of 50 to 85

NTSC4.43: TV standard used in Middle East countries.

• The supplied card remote control can be used without a cable,
and you can even use the optional full function remote control
and mouse adapter to operate your PC or Macintosh mouse
wirelessly from across the room with the built-in remote mouse
receiver.

• 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 kinds of pointers are available for your presentation.

• USB terminal allows USB mouse operation*4.

2. INSTALLATION

This section describes how to set up your MultiSync LT84/LT140
projector and how to connect video and audio sources.

Setting up Your Projector

Your MultiSync LT84/LT140 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 in the supplied
soft carrying case.

NOTE: Do not put a notebook computer in the soft carrying case.
Doing so can cause damage to the computer. When moving the pro­jector or when it is not in use, cover the lens cap.

Screen

Top view

Screen

Side view

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.)

5. To center the image vertically, lift the front edge of the projector
and press the One-Push Tilt buttons on the front side of the pro­jector, just above the feet, to release the Front Adjustable feet.
(There is approximately 5 degrees of up and down adjustment for
the front of the projector.)

6. If necessary, adjust the front or rear feet to properly position the
projected image on the screen.
If the projected image does not appear square to the screen then
use keystone correction for proper adjustment. The Lever-Type
Adjustable Rear foot height can be changed up to 3 degrees.

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 41˚F (5˚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-23.)

To connect to a PC or Macintosh, simply:

1. Turn off the power to your projector and computer.

2. Use the signal cable that’s supplied to connect your PC or
Macintosh computer to the projector. For older Macintosh, use
the supplied pin adapter to connect to your Mac's video port.

NOTE:The new Macintosh computer such as G3 will have the 15
pin HD connector. The LT84/LT140's "Plug and Play" data will
be downloaded to the Macintosh. Therefor e, the Mac adapter will
not be necessary.

3. Turn on the projector and the computer.

4. If the projector goes blank after a period of inactivity, it may be
caused by a screen saver installed on the computer you’ve con­nected to the projector.

Optional serial cable

Commercially available

NOTE: When using with a notebook PC, be
sure to connect between the projector and
the notebook PC before turning on the power
to the notebook PC. In most cases signal
cannot be output from RGB output unless the
notebook PC is turned on after connecting
with the projector.

E–16

When using a Macintosh with the projector, set the DIP switches of
the supplied pin adapter according to your resolution. After setting,
restart your Macintosh.
See the following pages for setting of the DIP switches.

• When using with a Macintosh, SVGA(8002600)/
XGA(10242768) is recommended if your Macintosh supports
this mode.

• When using with a Macintosh PowerBook, output may not be
set to 8002600 unless “mirroring” is off on your PowerBook.
Refer to owner’s manual supplied with your Macintosh com­puter for mirroring.

This is the name of a card currently being standardized by the Japan Electronic Industry Association (JEIDA) and
PCMCIA (Personal Computer Memory Card Interface Association) of the United States.

A type of PC card. AT A w as originally a type of interface between computers and fix ed disk de vices. The ATA card
is a standard card-type recording medium.

CompactFlash card is a small removable card conforming to ATA specifications. It is one-fourth the volume of a
PCMCIA card.

PCMCIA 2.1 PC cards are divided into three types according to their thickness: Type I (3.3 mm), T ype II (5.0 mm)
and Type III (10.5 mm).

A type of image format. The standard Windows Bit Map format used for MS-DOS/Windows-compatible comput­ers.

A type of image format. "JPEG" is the abbreviation of Joint Photographic Experts Group. JPEG compression offers
efficient data storage. The data not required for displaying the image is identified and deleted. Since the data is
deleted, JPEG algorithms are said to be irreversible. This means that once the image is compressed, the decom­pressed image it is not the same as the original image.

• DO NOT TOUCH THE LAMP immediately after it has been
used. It will be extremely hot. Turn off the power to the pro­jector and 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 three lamp case screws. You could receive an elec­tric shock.

• The projector will turn off and go into stand by mode after
1100 hours of service. If this happens, be sure to replace the
lamp. If you continue to use the lamp after 1000 hours 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 screwdr iver goes into a free­wheeling condition and remove the lamp cover. The lamp cover
screw is not removable.

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

3. Remove the lamp housing by pulling out the handle.

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

5. Secure it in place with the three screws.
Be sure to tighten the three screws.

CAUTION: Do not use a lamp other than the NEC replace­ment lamp (LT40LP).
Order this from your NEC dealer.

6. Reattach the lamp cover.

7. Tighten the lamp cover screw.

Be sure to tighten the lamp cover screw.

8. After you install a new lamp, select [Main Menu] → [Projector
Options] → [Setup]→[Page 2]→[Clear Lamp Hour Meter] to re-
set the lamp usage hours.

If the projector will not turn on after 1100 hours of service, press
and hold the “Help” button on the remote control for ten seconds
or longer to reset the lamp time clock to zero.

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