     WARNING
¥Only use your LCD 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 LCD projector where temperatures vary greatly. The projector must be used at temperatures between 32ûF
(0ûC) and 104ûF (40ûC).
¥
Do not expose the LCD projector to moisture, dust, or smoke. This will harm the screen image.
¥Ensure that you have adequate ventilation around your LCD projector so heat can dissipate. Do not cover the vents on the side
or the front of the projector.
Ceiling Installation
Installing your MultiSync MT830/1030 LCD 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.
NOTE : Distances may vary ±5%.

Reflecting The Image
Using a mirror to reflect your LCD projectors image enables you to enjoy a
much larger image. Contact your NEC dealer if you need a mirror.
If youre using a mirror and your image is inverted, use the ÒMenuÓ and

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 you were projecting the image from the front.
Contact your NEC dealer if you need a transparent screen.
If youre projecting the image from the rear and your image is inverted, use the

1. Plug the serial cable with the mouse output port of the projector into your computers mouse port and restart your computer to gain remote
mouse control.
2. When using the remote controls built-in infrared mouse on a laptop computer, the laptops mouse, trackball or trackpad will be disabled.
Disconnect the serial cable from the mouse output port and restart your computer to regain trackball or trackpad mouse control.
3. If the screen goes blank while using your remote control, it may be the result of the computers screen-saver or power management
software.
4. If you accidentally hit the OFF button on the remote control, wait one full minute and then press the ON button to resume.

Connecting Your PC Or Macintosh
Computer
Connecting your PC or Macintosh computer to your MultiSync
MT830 (SVGA) /1030 (XGA) Projector will enable you to project
your computers screen image for an impressive presentation. All of
these following display standards are supported:
To connect to a PC, Macintosh or computer equipped with an XGA/
SVGA /VGA adapter or compatible graphics adapter, simply:
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
computers owners manual for your XGA/SVGA/VGA configura-
tion. If you need to install a new board, see the manual that comes
with your new graphics board for installation instructions.

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
13Ó 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 connec-
tor) and then restart your Macintosh.
3. Use the signal cable thats supplied to connect your PC or
Macintosh computer to the projector. For a Macintosh, use the
supplied pin adapter to connect to your Macs 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 youve
connected to the projector.
When using a Macintosh with the MT830/1030, set the DIP
switches of the supplied pin adapter according to your resolution.
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 10242768 unless ÒmirroringÓ is off on your PowerBook.
Refer to ownerÕs manual supplied with your Macintosh com-
puter for mirroring.
NOTE: A Video Adapter cable manufactured by Apple Computer
is needed for a PowerBook which does not have a mini D-Sub 15-
pin connector.

Changing Video Resolutions
Depending on your computers 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:
6402480 at 16.7 million colors (24 bit Truecolor)
8002600 at 65 thousand colors.
10242768 at 256 colors.
As the resolution increases,  the number of colors you can run
decreases.  With 2 meg. of memory a computer will run:
6402480 at 16.7 million colors (24 bit Truecolor).
8002600 at 16.7 million colors (24 bit Truecolor).
10242768 at 65 thousand colors.
128021024 at 256 colors.
Windows 95
There are two methods you can use to change your resolution.
Method 1
1. Move your cursor to the background image and click.
2. In the Properties menu, select Settings.
3. Change your resolution and click OK.4. You may be asked to reboot for the changes to take affect, or you ll

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.
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 notebooks display, the timing parameters are a bit more like the
real VESA or VGA signal.
For an optimal projected image with a notebook computer, it is
recommended that you use the Auto mode. This feature is useful when
an XGA image (10242768) is displaying with a notebook computer
supported by SXGA (128021024) and when an SVGA image
(8002600) is displaying with a note book computer supported by
XGA (10242768). See Source Menu on page 61 for more
information.

Connecting Your Document Camera
You can connect your MultiSync MT830/1030 LCD Projector to a document camera. To do so, simply:
1. Turn off the power to your LCD projector and document camera.
2. Use a standard video cable to connect your document camera to the Video input on your projector.
3. Turn on the LCD projector and the document camera.

output requirements .
Connecting Your VCR Or Laser Disc Player
Use common RCA cables (not provided) to connect your VCR or laser disc player to your MultiSync
MT830/1030 LCD Projector. To make these connections, simply:
1. Turn off the power to your LCD projector and VCR or laser disc player.
2. Connect one end of your RCA cable to the video output connector on the back of your VCR or laser disc
player, connect the other end to the Video input on your projector. Use standard RCA audio patch cords
to connect the audio from your VCR or laser disc player to your projector (if your VCR or laser disc
player has this capability). Be careful to keep your right and left channel connections correct for stereo
sound.
3. Turn on the LCD projector and the VCR or laser disc player.
NOTE: Refer to your VCR or laser disc player owners manual for more information about your
equipments video output requirements.
Connecting An External Monitor
You can connect a separate, external monitor to your LCD projector to simultaneously view on a monitor
the image youre projecting. To do so:
1. Turn off the power to your LCD projector, monitor and computer, document camera or video source.
2. Use a 15-pin cable to connect your monitor to the RGB Monitor Output (Mini D-Sub 15 pin)
connector on your LCD projector.
3. Turn on the LCD projector, monitor and the computer, document camera or video source.

Mouse Output Port
The built-in remote mouse receiver enables you to operate your
computers mouse functions from the NEC MultiSync MT830/1030
remote control. It is a great convenience for clicking through your
computer-generated presentations.
To connect the mouse output port:
1. Turn off your computer.
2. For PCs: Remove your current mouse and connect the serial
cable from the mouse output to your PCs mouse port. (Use the
6-pin adapter for connecting to a PS/2 computer.)
For Macintosh: Remove your current mouse from your com-
puter, attach the Macintosh adapter to the mouse output portÕs
serial cable, and connect the LCD Projector to your mouse port.
3. When the built-in remote mouse receiver is available, it will
disable your regular mouse, disconnect the serial cable and
restart your computer.
