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.  
Lamp Replacement  
• 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.  
Installation  
1. For best results, use your LCD 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 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.  
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.  
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 LCD  
projector. Allow at least 10cm (3 inches) of space between your  
LCD projector and a wall.  
5. Handle your LCD projector carefully. Dropping or jarring can  
damage internal components.  
6. Do not place heavy objects on top of the LCD projector.  
7. If installing the LCD projector on the ceiling:  
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, disconnect it immedi-  
ately and have the object removed by a qualified NEC service  
person.  
a. The ceiling must be strong enough to support the LCD projec-  
tor and the installation must be in accordance with any local  
building codes.  
b. The LCD projector must be installed by qualified NEC service  
personnel.  
3. Do not place any liquids on top of your LCD projector.  
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.  
• 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.  
2. Handle the power cable carefully and avoid excessive bending. A  
damaged cord can cause electric shock or fire.  
3. If the LCD projector is not to be used for an extended period of  
time, disconnect the plug from the power outlet.  
Cleaning  
1. Unplug the LCD 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.  
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.

The MultiSync MT1020G/820G is one of the very best LCD  
projectors available today. The multiple LCD panels enable  
you to project precise images up to 300 inches across (mea-  
sured diagonally) from your PC or Macintosh computer  
(desktop or notebook), VCR, document camera, or even a  
laser disc player.  
You can use the projector on a tabletop or cart, you can  
permanently mount it on a ceiling*1, or you can use  
MultiSync MT1020G/820G LCD Projector to project im-  
ages from behind the screen. The remote control can be used  
wirelessly or with a cable, and you can even use the remote  
control with the remote mouse receiver to operate the mouse  
on your PC or Mac. But best of all, the MultiSync  
MT1020G/820G is an NEC LCD projector. That means you  
can depend on years of reliable performance and crystal-  
clear presentations!

• The remote control can be used with or without a cable,  
and you can even use the remote to operate your PC or  
Macintosh mouse wirelessly from across the room with  
the remote mouse receiver.  
You can control your MultiSync MT1020G/820G LCD  
Projector with a PC.  
The features you’ll enjoy include:  
• Simple set up and operation.  
• The contemporary cabinet design is compact, easy to  
carry, and complements any office, board room or audito-  
rium.

cians.  
• A high-performance 250 watt metal halide lamp that  
delivers 700 ANSI lumens (MT1020G: 600 ANSI lu-  
mens) and is guaranteed for 2000 hours of service or six  
months, whichever comes first.  
• A wireless remote control that operates the projector from  
any angle.  
Consult your NEC dealer for more information.

5. Choose the current drive or another.  
1024 x 768 at 256 colors.  
6. Restart Windows for the changes to take affect.  
As the resolution increases, the number of colors you can run  
decreases. With 2 meg. of memory a computer will run:  
640 x 480 at 16.7 million colors (24 bit Truecolor).  
800 x 600 at 16.7 million colors (24 bit Truecolor).  
1024 x 768 at 65000 colors.  
Macintosh

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 realVESA  
or VGA signal.  
4. You may be asked to reboot for the changes to take affect,  
or you' ll get a message that "Windows is about to resize  
your display." You' ll be asked if you want to keep your  
settings. Select "Yes."  
Method 2  
1. Click on your "My Computer" icon.  
2. Open "Control Panel" and select "Display."  
3. Change your resolution and click "OK." after the new

M A I N T E N A N C E  
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.  
CAUTION  
Step 1A  
Step 1B  
• 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 be in standing by 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 circumvent this interlock.)  
3. Remove the lamp by pulling out the complete assembly.  
Step 3  
Step 4  
4. Install a new lamp case assembly and secure it in place with the  
two screws.  
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 .  
Step 5  
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.  
CAUTION: Do not put the LCD projector on end except to  
replace the air filter.

Cleaning Or Replacing The Filter  
The air-filter sponge keeps the inside of the MultiSync MT1020G/  
820G LCD 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.  
NOTE: Clean your filter after every 100 hours of operation.  
CAUTION  
• Turn off the LCD projector and wait for the fan to stop. Turn  
off the main 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.  
• Your LCD projector will not operate unless the filter is in-  
stalled 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 phillips until you feel it detach.  
2. Remove the filter and replace it.  
3. Reinstall the filter panel.  
NOTE: Do not detach the sponge from the filter cover. Do not wash the  
filter with soap and water. Soap and water will damage the filter  
membrane.  
Before replacing the air-filter, remove dust and dirt from the  
projector cabinet. Keep them out during filter replacement.  
Remote Control Battery Installation  
1. Press firmly and slide the battery cover off.  
2. Remove all two old batteries and install new ones (AA). Ensure  
that you have the batteries' polarity (+/–) aligned correctly.  
3. Slip the cover back over the batteries until it snaps into place.
