Important Safeguards  
Lamp Replacement  
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.  
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.  
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.  
• Allow a minimum of ONE minute to elapse after turning off the pro-  
jector. Then disconnect the power cable and allow 60 minutes to  
cool the projector before replacing the lamp.  
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 com-  
ponents.  
5. Handle your projector carefully. Dropping or jarring can damage in-  
ternal 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.  
Fire and Shock Precautions  
1. Ensure that there is sufficient ventilation and that vents are unob-  
structed 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 re-  
moved 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.  
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.  
• Keep any items such as magnifying glass out of the light path of the  
projector.The light being projected from the lens is extensive, there-  
fore 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.  
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.  
• 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.  
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 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 con-  
tinues 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 MultiSync LT156/LT155/LT154 projector and how to connect video and audio sources.  
Setting up Your Projector  
Your MultiSync LT156/LT155/LT154 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 3.7 feet (1.1 m) from the wall or screen. The largest the image can be is 300" (7.6 m) when the  
projector is about 40.1 feet (12.2 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.

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 in-  
jured and the projector severely damaged.  
• Do not use the projector where temperatures vary  
greatly. The projector must be used at tempera-  
tures 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-37.)  
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.)

4. MAINTENANCE  
This section describes the simple maintenance procedures you should  
follow to replace the lamp and clean the filter.  
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  
(LT55LP). Order this from your NEC dealer.  
Replacing the Lamp  
After your lamp has been operating for 1000 hours (2000 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, re-  
place it at 1000 (2000 hours : Eco mode) hours to maintain optimal  
projector performance.  
Secure it in place with the two screws.  
Be sure to tighten the screws.  
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 1100 (2200  
hours : Eco mode) hours of service. If this happens, be sure to replace  
the lamp. If you continue to use the lamp after 1000 hours (2000 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.  
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 screw-  
driver 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.  
5. After you install a new lamp, select [Menu] [Projector Op-  
tions] [Setup][Page 4][Clear Lamp Hour Meter] to reset  
the lamp usage hours.  
NOTE: When the lamp exceeds 1100 hours (2200 hours : Eco mode) of ser-  
vice, 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.
