Important Safeguards  
These safety instructions are to ensure the long life of your LCD projector and  
to prevent fire and shock. Please read them carefully and heed all warnings.  
7. If installing the LCD projector on the ceiling:  
a. The ceiling must be strong enough to support the LCD projector and the  
installation must be in accordance with any local building codes.  
Installation  
1. For best results, use your LCD projector in a darkened room.  
b. The LCD projector must be installed by qualified NEC service personnel.  
2. Place the projector on a flat, level surface in a dry area away from dust and  
moisture.  
Power Supply  
1. The LCD projector is designed to operate on a power supply of 100-120 or  
220-240 V 50/60 Hz AC. Ensure that your power supply fits this requirement  
before attempting to use your LCD projector.  
3. Do not place your LCD 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 LCD projector carefully. Dropping or jarring can damage  
internal components.  
2. Handle the power cable carefully and avoid excessive bending. A damaged  
cord can cause electric shock or fire.  
6. Do not place heavy objects on top of the LCD projector.  
3. If the LCD projector is not to be used for an extended period of time,  
disconnect the plug from the power outlet.  
Cleaning  
Fire and Shock Precautions  
1. Unplug the LCD projector before cleaning.  
1. Ensure that there is sufficient ventilation and that vents are unobstructed to  
prevent the build-up of heat inside your LCD projector. Allow at least 3  
inches (10cm) of space between your LCD projector and a wall.  
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.  
4. Clean the air filter with a vacuum cleaner after every 100 hours of operation.  
a. Clean the outside of the filter with a vacuum cleaner.  
b. Do not use water or any other liquid to clean the air filter.  
c. Do not operate your LCD projector without the air filter.  
2. Prevent foreign objects such as paper clips and bits of paper from falling into  
your LCD 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 LCD project. If something should fall into your projector, discon-  
nect it immediately and have the object removed by a qualified NEC service  
person.  
Lamp Replacement  
3. Do not place any liquids on top of your LCD projector.  
• Be sure to replace the lamp when the Status light comes on. If you continue  
to use the lamp after 2000 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.  
• Do not look into the lens while the projector is on. Serious  
damage to your eyes could result.  
• 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.  
• Allow a minimum of ONE minute to elapse between turning the lamp off and  
on. High voltage is applied to the lamp immediately when the power is turned  
on. Therefore turning the power off and quickly back on may shorten the life  
of your lamp and result in damage to your LCD projector.

d’utilisation, l’ampoule peut se briser et des brisures de verre peuvent être  
éparpillées dans le compartiment de la lampe. Ne les touchez pas car elles  
peuvent vous blesser. Dans ce cas, contactez votre revendeur NEC afin de  
procéder au remplacement de la lampe.  
3. Ne pas placer des liquides sur le dessus du projecteur à écran à cristaux  
liquides (LCD).  
• Attendez minimum UNE minute après avoir éteint la lampe avant de la  
rallumer. Une haute tension est immédiatement appliquée à la lampe quand  
celle-ci est mise sous tension. Par conséquent, éteindre, puis tout de suite  
rallumer peut abréger la vie de votre lampe et endommager votre projecteur  
LCD.  
• Ne regardez pas à l’intérieur de l’objectif lorsque le projecteur  
est en marche. Vous risquez de vous blesser gravement aux  
yeux.  
• Ne regardez pas à l’intérieur de la flèche laser lorsque celle-ci  
est en marche et ne dirigez pas le rayon laser sur une autre  
personne. Vous risquez de provoquer ue blessure grave.  
Précautions pour éviter un incendie ou  
une électrocution  
1. Une ventilation appropriée doit être assurée afin d’éviter une accumulation  
de chaleur à l’intérieur du projecteur à écran à cristaux liquides (LCD).  
S’assurer que les trous de ventilation ne sont pas obstrués. Laisser un espace  
d’au moins 10 cm (quatre pouces) entre le projecteur à écran à cristaux  
liquides (LCD) et les murs.

Setting Up Your MultiSync MT1020/MT820  
LCD Projector  
Your MultiSync MT1020/MT820 LCD Projector is simple to set up and use.  
But before you get started, you must first:  
Push to release the  
handle.  
1. Determine the image size  
2. Set up a screen or select a non-glossy white wall onto which you can project  
your image.  
Pull out  
Carrying The LCD Projector Always carry your LCD projector by the  
handle. Ensure that the power cord 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.  
Push to retract  
Selecting A Location The further your LCD projector is from the screen or  
wall, the larger the image. The minimum size the image can be is approxi-  
mately 20" (0.5 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 40.03 feet (12.2 m) from the wall or screen.

Notebook Computers And Resolution Standards  
NEC projectors are designed to project industry standardized video  
such as VESA (Video Electronics Standards Association) or VGA  
(Video Graphics Array). Notebook computers do not use industry  
standards. They use whatever timing is necessary to match their local  
LCD display. The end result is typically not standards. By turning off  
your notebook's display, the timing parameters are a bit more like the  
real VESA or VGA signal.  
1. Under the Apple menu, select "Control Panels" and open "Moni-  
tors."  
2. Click and open "Options."  
3. Select your new resolution and click "OK."  
If you have an NEC monitor connected to your Macintosh, you may  
have a "DPI-On-The-Fly" extension that enables you to change your  
resolution directly. The "DPI-On-The-Fly" icon is under your Apple  
menu.  
For an optimal projected image with a notebook computer, it is  
recommended that you use the CUSTOM 6 memory data. This feature  
is useful when an XGA image (1024
ן
768) is displaying with a  
notebook computer supported by SXGA (1280
ן
1024) and when an  
SVGA image (800
ן
600) is displaying with a note book computer  
supported by XGA (1024
ן
768). See Source Menu on page 52 for  
more information.

This section describes the simple maintenance procedures you should follow  
to replace the lamp, clean or replace the filter, and replace the batteries in the  
remote control.  
Replacing The Lamp  
After your lamp has been operating for 2000 hours or longer, the  
“status” light in the cabinet will go on. Even though the lamp may still  
be working, replace it at 2000 hours to maintain optimal projector  
performance.  
Step 1A  
Step 1B  
CAUTION  
• DO NOT TOUCH THE LAMP immediately after it has been used. It will  
be extremely hot. Allow at least one hour for the lamp to cool before  
handling.  
• DO NOT REMOVE ANY SCREWS except the lamp cover set screw  
and two lamp case screws. You could receive an electric shock.  
• Turn off the main power to the projector and disconnect the power cord.  
Allow at least one hour for the lamp to cool.  
• The projector will turn off and go into stand by mode after 2100 hours of  
service. If this happens, be sure to replace the lamp. If you continue to  
use the lamp after 2000 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.  
Step 2  
Interlock  
To replace the lamp:  
1. Remove the single screw that secures the lamp housing cover and remove  
the cover.  
2. Remove the two screws securing the lamp case. (There is an interlock on  
this case to prevent the risk of electrical shock. Do not attempt to circum-  
vent this interlock.)  
3. Remove the lamp by pulling out the complete assembly.  
4. Install a new lamp case assembly and secure it in place with the two screws.  
Step 3  
Step 4  
CAUTION: Do not use a lamp other than the NEC replacement lamp.  
Order this from your NEC dealer using your projector's model number.  
5. Reattach the lamp cover and reinstall the single screw.  
6. After you install a new lamp, select the lamp Usage icon and press and hold  
the "Power On" button on the remote control for ten seconds to reset the  
lamp time clock to zero.  
NOTE: If resetting the lamp clock back to zero after 2100 hours of service, press  
the "Power Off" (not "Power On") button on the remote control for ten seconds .  
NOTE: When you replace the lamp, it is also wise to replace the filter. The filter  
comes in the same package with your replacement lamp.  
Step 5  
CAUTION: Do not put the LCD projector on end except to replace the air  
filter.

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.  
• Your LCD projector will not operate unless the filter is installed correctly.  
• Do not put the LCD projector on end except to replace the filter.  
To clean the air-filter:  
1. Turn over the projector. Put the LCD projector on end so that the bottom is visible.  
2. Vacuum the filter through the filter cover.  
3. Place the projector back in a horizontal position.  
To replace the air-filter:  
1. Remove the filter panel by pushing up on the catch of the cover with a flat-head screwdriver until  
you feel it detach.  
2. Remove the filter and replace it.  
3. Reinstall the filter panel.
