Connecting Your PC Or Macintosh Computer
Connecting your PC or Macintosh computer to your MultiSync MT810 LCD Projector
will enable you to project your computer's screen image for an impressive presentation.
All of these following display standards are supported:
VGA 640 X 480 for graphics VGA 640 X 400 for graphics
VGA 640 X 350 for graphics VGA 720 X 400 for text
VGA 720 X 350 for text SVGA 800 x 600
Macintosh at 640 x 480 Macintosh at 832 X 624
To connect to a PC, Macintosh or computer equipped with an SVGA/VGA adapter or
compatible graphics adapter, simply:
1. Turn off the power to your LCD projector and computer.
2. If your PC does not support SVGA/VGA you will need to install an SVGA/VGA
graphics board. Consult your computer's owner's manual for your SVGA/VGA
configuration. If you need to install a new board, see the manual that comes with
your new graphics board for installation instructions.
W
. Use the MultiCable that's supplied to connect your PC or Macintosh computer to the
LCD projector. For a PC, use the smaller 15-pin connector on the cable to connect to
your computer's video port; use the larger 15-pin connector on the cable to connect
to the projector's RGB | input. For Macintosh, use the larger 15-pin connector on the
cable to connect to your computer's video port; use the smaller 15-pin connector on
the cable to connect to the projector's RGB 2 input. (You can also use your own
video cable if you wish. For a PC cable, use the smaller 15-pin connector RGB 2 on
the projector. For a Macintosh cable, use the larger 15-pin connector RGB 1 on the
projector.)
+
Turn on the LCD projector and the computer.
wv
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.
NOTE: Refer to your computer's owner's manual for more information about your
computer's video output requirements and any special identification or configuring vour
projector's image and monitor may require.

OPERATION

USERS MANUAL
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.
A 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. Interlock
To replace the lamp:
1. Remove the single screw that secures the lamp housing cover and remove
the cover.
. 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.)
. Remove the lamp by pulling out the complete assembly.
. Install a new lamp case assembly and secure it in place with the two screws.
A\ CAUTION: Do not use a other than the NEC replacement lamp.

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.

Cleaning Or Replacing The Filter
The air-filter sponge keeps the inside of the MultiSync MT810 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 installed correctly.
* Do not put the LCD projector on end except to replace the filter.
To clean the air-filter:
1. Tum 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.
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 out dust
and dirt during filter replacement.

2. Remove both old batteries and install new ones (AA). Ensure that you have the batteries’ polarity
