This is the name of a card currently being standardized by the Japan Electronic Industry Association (JEIDA) and
PCMCIA (Personal Computer Memory Card Interface Association) of the United States.
PCMCIA 2.1 PC cards are divided into three types according to their thickness:  Type I (3.3 mm), Type II (5.0 mm)
and Type III (10.5 mm).
A type of image format.  The standard Windows Bit Map format used for MS-DOS/Windows-compatible comput-
ers.
A type of image format.  JPEG is the abbreviation of Joint Photographic Experts Group.  JPEG compression offers
efficient data storage.  The data not required for displaying the image is identified and deleted.  Since the data is
deleted, JPEG algorithms are said to be irreversible.  This means that once the image is compressed, the decom-
pressed image it is not the same as the original image. PC card

4. MAINTENANCE
This section describes the simple maintenance procedures you should
follow to replace the lamp, clean the filter, and replace the batteries
in the remote control.
Replacing the Lamp
After your lamp has been operating for 2000 hours (1500 hours :
MT1045) or longer, the ÒStatusÓ light in the cabinet will go on and
the message will appear. Even though the lamp may still be working,
replace it at 2000 (1500 hours : MT1045) hours to maintain optimal
projector performance.
CAUTION
¥ DO NOT TOUCH THE LAMP immediately after it has been
used. It will be extremely hot. Turn the projector off, wait a
full minute, and then disconnect the power cable. Allow at
least one hour for the lamp to cool before handling.
¥ DO NOT REMOVE ANY SCREWS except the lamp cover
screw and three lamp case screws. You could receive an elec-
tric shock.
¥
The projector will turn off and go into stand by mode after 2100
(1600 hours : MT1045) hours of service. If this happens, be sure
to replace the lamp. If you continue to use the lamp after 2000
hours (1500 hours : MT1045) 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 hap-
pens, contact your NEC dealer for lamp replacement.
To replace the lamp:
1. Loosen the lamp cover screw until the screwdriver goes into a free-
wheeling condition and remove the lamp cover. The lamp cover
screw is not removable.

Cleaning or Replacing the Filters
The air-filter sponge keeps the inside of the MultiSync MT840/
MT1040/MT1045 Projector free from dust or dirt and should be
cleaned after every 100 hours of operation (more often in dusty con-
ditions). If the filter is dirty or clogged, your projector may overheat.
CAUTION
¥ Turn off the power and unplug the projector before re-
placing 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 projector will not operate unless the filter cover is
installed correctly.
To clean the air-filter:
Vacuum the filter-through the filter cover.

¥ Are slide data stored in the PC card?
¥ Have the contents of the PC card been destroyed?
¥ While an image with over 10242768 dots is projected, several lines of information will be lost. Use the
supplied software change the image to 10242768 dots in size.
¥ Areas of slides exceeding 10242768 (MT840: 8002600 dots)  cannot be displayed.  Use the PC Card
Viewer software, etc., to change the image size to 10242768 dots (MT840: 8002600 dots).
