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.  
CAUTION  
2. Handle the power cable carefully and avoid excessive bending. A  
damaged cord can cause electric shock or fire.  
To turn off main power, be sure to remove the plug  
from power outlet. The power outlet socket should be  
installed as near to the equipment as possible, and should  
be easily accessible.  
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.

ISO 7779.  
E-2  
Lamp Replacement  
• Perform lamp replacement in accordance with the instructions on  
page E-37.  
• 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.  
• 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.  
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 LCD projector.  
Allow at least 3 inches (10cm) of space between your LCD projector  
and a wall.  
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 immediately and have the  
object removed by a qualified NEC service person.  
3. Do not place any liquids on top of 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.

1 INTRODUCTION  
This section introduces you to your new MultiSync MT830  
(SVGA) / 1030 (XGA) LCD Projector, provides a list of  
materials that comes with your projector and describes the  
features and controls.  
An image can be projected from in front or behind a  
screen, and the projector can even be installed on the  
ceiling.  
NEC Technologies' exclusive AccuBlend intelligent pixel  
blending technology - an extremely accurate image com-  
pression technology - offers a crisp image with SXGA  
(1280
ן
1024) resolution*3. You can select any point on  
the screen with the pointer and enlarge the selected area.  
Congratulations On Your Purchase Of The  
MultiSync  
MT830/1030 LCD Projector  
Supports most IBM VGA, SVGA, XGA, SXGA(with  
AccuBlend)*3, Macintosh, or any other RGB signals within a  
horizontal frequency range of 15.625 to 85 kHz and a vertical  
frequency range of 50 to 85 Hz. This includes NTSC, PAL,  
The MultiSync MT830/1030 is one of the very best LCD  
projectors available today. The multiple LCD panels enable  
you to project precise images up to 300 inches (762 cm)  
across (measured diagonally) from your PC or Macintosh  
computer (desktop or notebook), VCR, DVD player, docu-  
ment camera, or even a laser disc player.  
SECAM and NTSC4.43 standard video signals.

NTSC:  
PAL:  
SECAM: TV standard used in France and Eastern Europe.  
NTSC4.43: TV standard used in Middle East countries.  
U.S. TV standard for video in U.S. and Canada.  
TV standard used in western Europe.  
You can use the projector on a tabletop or cart, you can  
permanently mount it on a ceiling*1, or you can use  
MultiSync MT830/1030 LCD Projector to project images  
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 built-in remote mouse receiver to operate the  
mouse on your PC or Mac. But best of all, the MultiSync  
MT830/1030 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 built-in remote mouse receiver.  
You can control your MultiSync MT830/1030 LCD Pro-  
jector with a PC.  
The contemporary cabinet design is compact, easy to  
carry, and complements any office, board room or audito-  
rium.  
Eight kinds of pointers are available for your presentation.  
Features you’ll enjoy:  
*1 Installing the MultiSync MT830/1030 LCD Projector on  
the ceiling must be done by authorized NEC technicians.  
Consult your NEC dealer for more information.  
Simple set up and operation.  
Hot air blown from the vents does not bother the audience  
during your presentation since the vents are located on the  
front.  
*2 An XGA image (1024
ן
768) is converted into an  
800
ן
600 crisp image with NEC technology's AccuBlend.  
A high-performance 150 watt short arc high pressure lamp  
that delivers 1000 ANSI lumens (MT1030: 900 ANSI  
lumens) and an operating lamp life is 2000 hours.  
*3 An SXGA image (1280
ן
1024) is converted into a  
1024
ן
768 crisp image with NEC technology's  
AccuBlend.  
A wireless remote control that operates the projector from  
any angle.  
A laser pointer that' s built into the remote control.  
The power zoom control enables you to adjust the image  
to be between 50.8 and 762 cm (measured diagonally).  
Keystone correction allows you to correct trapezoidal dis-  
tortion so that the image is square.  
White balance control allows you to adjust the brightness  
and contrast for each RGB color.  
You can choose between video modes depending on your  
source: "normal" for a typical picture, "natural" for true  
color reproduction, and "camera" for use with a document  
camera or low APL picture.  
The optional MT Viewer kit allows you to start your  
presentation even when a PC is not available at the site.  
The "image capture" enables you to use the entire picture  
as a background image or to create slides (optional MT  
Viewer required).

2. Set up a screen or select a non-glossy white wall onto which  
you can project your image.  
Carrying The LCD Projector Always carry your LCD projec-  
tor 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.  
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 approximately 0.5 m (20") measured diago-  
nally when the projector is roughly 1.0 m from the wall or  
screen. The largest the image can be is 7.6 m (300") when the  
projector is about 12.2 m from the wall or screen.

Using A Tabletop Or Cart  
1. Place your LCD 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.)  
(A) Top view  
screen  
2. Connect the power cable, remove the lens cap and turn the  
projector on. (If no input signal is available, the projector will  
display a background image.)  
3. Ensure that the projector is square to the screen.  
(B) Side view  
screen  
4. Move the projector left or right to center the image horizon-  
tally on the screen. (A)  
5. To center the image vertically (B), lift the front edge of the  
projector and press the buttons on the front of the projector,  
just above the feet, to release the one-touch tilt feet. (There is  
approximately 10.5˚ of up and down adjustment for the front  
of the projector. )  
6. If a trapezoidal distortion appears on the screen, use the  
KEYSTONE button on the remote control or select Key-  
stone from the menu to correct the distortion.  
If necessary, adjust the front or rear feet so that the lens  
surface is parallel to the screen. If you use the projector with  
the screen tilted, the picture will be distorted. Each of the rear  
feet height can be changed up to 4 mm.  
7. Increase or reduce the size of the projected image by press-  
ing the "Zoom" (+) or (–) buttons on the remote control or  
top of the cabinet.

Rear Screen Projection  
You can use your MultiSync MT830/1030 LCD projector to  
project an image from the rear onto a transparent screen. The  
distance the projector must be from the screen is the same as if

To connect to a PC, Macintosh or computer equipped with an  
XGA/SVGA /VGA adapter or compatible graphics adapter,  
simply:  
NOTE: For settings other than display modes supported by your  
Macintosh and MT830/1030, use of the DIP switch may bounce a  
image slightly or may display nothing. If this happens, set the DIP  
switch to the 13” fixed mode and then restart your Macintosh. After  
that, restore to a displayable mode and then restart the Macintosh  
again.  
Make sure that the MT830/1030 and your Macintosh are connected  
with the pin adapter and the supplied signal cable (mini D-Sub 15-  
pin connector) and then restart your Macintosh.  
1. Turn off the power to your projector and computer.  
2. If your PC does not support XGA/SVGA/VGA you will need  
to install an XGA/SVGA/VGA graphics board. Consult your  
computer's owner's manual for your XGA/SVGA/VGA con-  
figuration. If you need to install a new board, see the manual  
that comes with your new graphics board for installation  
instructions.  
3. Use the signal cable that's supplied to connect your PC or  
Macintosh computer to the projector. For a Macintosh, use  
the supplied pin adapter to connect to your Mac's video port.  
4. Turn on the projector and the computer.  
5. 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.  
When using a Macintosh with the MT830/1030, set the DIP  
switches of the supplied pin adapter according to your resolu-  
tion. After setting, restart your Macintosh.  
See the following pages for setting of the DIP switches.  
When using with a Macintosh, XGA/VGA/SVGA is recom-  
mended if your Macintosh supports this mode.  
• When using with a Macintosh PowerBook, output may not  
be set to 1024
ן
768 unless “mirroring” is off on your  
PowerBook. Refer to owner’s manual supplied with your  
Macintosh computer for mirroring.  
NOTE: A Video Adapter cable manufactured by Apple Com-  
puter is needed for a PowerBook which does not have a mini D-  
Sub 15-pin connector.

Changing Video Resolutions  
1. Under the Apple menu, select "Control Panels" and open  
"Monitors."  
2. Click and open "Options."  
Depending on your computer's graphic capability, you may be  
able to select one of several resolutions. Generally a computer-  
either a PC or Macintosh- with 1 meg. of memory will run:  
640
ן
480 at 16.7 million colors (24 bit Truecolor)  
800
ן
600 at 65 thousand colors.  
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.  
1024
ן
768 at 256 colors.  
As the resolution increases, the number of colors you can run  
decreases. With 2 meg. of memory a computer will run:  
640
ן
480 at 16.7 million colors (24 bit Truecolor).

Notebook Computers And Resolution Standards  
NEC projectors are designed to project industry standardized  
video such as VESA (Video Electronics StandardsAssociation)  
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.

Projecting Pictures a Digital Camera Took  
Playing back on the LCD projector is possible if a picture meets  
one of the following requirements:  
* A picture that can be stored to an MS-DOS-formatted ATA  
flash memory card  
NOTE: Editing tasks such as deleting the data inside the flash  
memory card cannot be accomplished with the LCD projector.  
Use the exclusive software on your PC for this purpose. If you  
accidentally delete data required for playback, playing back  
the data is not possible.  
* A picture that can be stored as a compatible format  
The on-board Viewer searches for the directory on the card to  
recognize a JPEG or BMP format image as slide. Directories to  
be searched for are up to two level from the root directory and  
must be less than 16 directories. Although only switching folders  
and slides is possible, special effects and displaying a list is not  
possible.  
Effect Sound  
The Viewer function allows you to play back effect sound for the  
slide.  
Playing back effect sound can be accomplished during the  
switching slides or files only. To use this feature, you must first  
specify the effect sound with the supplied software.  
You can adjust volume by using the Volume button.  
NOTE:  
* Up to 128 images can be recognized as slides for one directory.  
* To use special effects, read images from a flash memory card  
and edit them using the supplied software, then store them to  
another flash memory card.  
* If you store indexes to the flash memory card for your digital  
camera using the supplied software, images taken with the  
digital camera cannot be viewed on the Viewer. So preparing  
flash memory cards for a digital camera and Viewer respec-  
tively is recommended.

4 MAINTENANCE  
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  
Step 1A  
Step 1B  
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  
• 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  
To replace the lamp:  
1. Loosen the single screw that secures the lamp housing cover  
and remove the cover.  
2. Loosen the two screws securing the lamp case.  
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 replace-  
ment lamp.  
Order this from your NEC dealer using your projector's  
model number.  
5. Reattach the lamp cover and tighten 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  
E-37  
Cleaning Or Replacing The Filter  
The air-filter sponge keeps the inside of the MultiSync MT830/  
1030 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 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  
cover.  
Your LCD projector will not operate unless the filter cover  
is installed correctly.  
To clean the air-filter:  
Vacuum the filter through the filter cover.  
To replace the air-filter:  
1. Remove the filter cover by pushing up on the catch of the  
cover with a flat-head screwdriver until you feel it detach.  
2. Reinstall the new filter cover.  
NOTE: Do not detach the sponge from the filter cover. Do not  
wash the filter cover with soap and water. Soap and  
water will damage the filter membrane.  
Before replacing the filter cover, remove dust and dirt  
from the projector cabinet. Keep out dust and dirt  
during filter replacement.  
Remote Control Battery Installation  
1. Press firmly and slide the battery cover off.  
2. Remove both old batteries and install new ones (AA). En-  
sure that you have the batteries' polarity (+/–) aligned cor-  
rectly.  
3. Slip the cover back over the batteries until it snaps into place.
