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 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 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.
Lamp Replacement
• To replace the lamp, follow all instructions provided on page E-48.
• 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 ONE minute 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.
• Do not look into the laser pointer while it is on and do not point the
laser beam at another person. Serious injury could result.
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 moment." appears. This message
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 orange glow).
• Immediately after the cooling fan stops working (The cooling fan continues to work for ONE minute after the projector is turned off with the
POWER button).
• While the POWER and the STATUS 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.

2. INSTALLATION
This section describes how to set up your LT158/LT157 projector and how to connect video and audio sources.
Setting up Your Projector
Your LT158/LT157 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" (0.6 m)
measured diagonally when the projector is roughly 3.9 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 40.4 feet (12.3 m) from the wall or screen.
Screen and Projection Distance
The following shows the proper relative positions of the projector and screen. Refer to the table to determine the position of installation.

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-37.)
Projector Foot
• 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.
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-37.)

* If you accidentally hit the POWER button on the remote control, wait 60 seconds and then press the POWER button again to resume.
NOTE: If using video, S-video, or audio cables, the cables should be 3 m (9.8 feet) or shorter.
For LT158:
When Viewing a DVI Digital Signal:
To project a DVI digital signal, be sure to connect the PC and the projector using the supplied DVI-D signal cable before turning on your PC or
projector. Turn on the projector first and select DVI (DIGITAL) from the source menu before turning on your PC.
Failure to do so many not activate the digital output of the graphics card resulting in no picture being displayed. Should this happen, restart your PC.
Do not disconnect the supplied DVI-D signal cable while the projector is running. If the signal cable has been disconnected and then re-connected,
an image may not be correctly displayed. Should this happen, restart your PC.
NOTE: Some personal computers or video cards may not display images correctly on the LT158.
To connect a DVI connector on your computer to LT158, attach the supplied DVI-D – DVI-D signal cable to the DVI connector on the projector. If you use a separately
sold DVI cable, images may not be correctly displayed.
NOTE: The DVI connector can accept a maximum resolution of 1024x768(XGA) when a DVI (DIGITAL) input is selected.

Digital images can be played with the PC Card Viewer if the following
conditions are met:
• If the image can be stored on an MS-DOS format CompactFlash
card
• If the image can be stored in a format supported by the PC Card
Viewer.
With the PC Card Viewer, images on the card are searched for in
directories and images in JPEG or BMP format are recognized as
slides.
Searchable directories are directories within two steps from the root
directory, and searchable images are images within the first 12 files
in the directory. Only file and slide switching are possible.
NOTE: The maximum number of images recognized as slides within one directory is 128.
NOTE: You can compress a captured file (JPEG) using the Capture Options in
the Setup dialog. See page E-37.
NOTE: Captured images with higher resolution than the projector's native resolution cannot be displayed correctly.
NOTE:
• File size of the captured image varies depending on the resolution of an
input signal.
• Since an image data is compressed with the JPEG format, the image is slightly
degraded.
NOTE: An hourglass indicating that an image is being captured appears on the
projector's display. Do not eject the CompactFlash card or turn off the projector's
power while this icon is displayed. Doing so will damage the CompactFlash
card data. If the CompactFlash card data is damaged, use a computer to repair
the data.
NOTE: The folder in the right bottom is always a folder exclusively for captured
images. To display the list of folders when there are 13 or more indexes stored
on the CompactFlash card, select "Edit index" from the PC Card Viewer software's
"File" menu and move the index you want to display to within 12 indexes from
the top of the folder index. For details on indexes, refer to the PC Card Viewer
software's help file.

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. ATA was originally a type of interface between computers and fixed disk devices. 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), Type 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.

4. MAINTENANCE
This section describes the simple maintenance procedures you should
follow to replace the lamp and clean the filter.
Replacing the Lamp
After your lamp has been operating for 1500 hours (2500 hours : 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 1500 (2500 hours : Eco 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 a full minute, 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 housing screws. You could receive an electric shock.
• The projector will turn off and go into stand by mode after 1600 (2600
hours : Eco mode) hours of service. If this happens, be sure to replace
the lamp. If you continue to use the lamp after 1500 hours (2500 hours
: Eco mode) of use, the lamp bulb may shatter, and pieces of glass may
be scattered in the lamp housing. 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.
3. Insert a new lamp housing .
CAUTION: Do not use a lamp other than the NEC replacement lamp
(LT57LP). 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.
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
5. After you install a new lamp, select [Menu] → [Projector Options] → [Setup]→[Page 4]→[Clear Lamp Hour Meter] to reset
the lamp usage hours.
NOTE: When the lamp exceeds 1600 hours (2600 hours : Eco mode) of service, the projector cannot turn on and the message 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.

rectly.
To clean the air-filter:
When “Clean Filter” option is turned on, the “Please clean the filter”
message will be displayed each time the project or is turned on after it
has been used in excess of 100 hours. Should this message appear,
clean the filter.
• The message can be turned on or off using the “Menu” - “Filter Clean
Message” option on the Setup menu. See page E-36.
• After cleaning the filter and resetting the filter usage time to zero, the
message will not be displayed.
See page E-38 for resetting the filter usage time.
