TYPE (I, II and III)

JPEGThis 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.
A type of PC card.  ATA was originally a type of interface between computers and fixed disk devices.  The ATA card is a standard
card-type recording medium.
CompactFlash card is a small removable card conforming to ATA specifications. It is one-fourth the volume of a PCMCIA card.
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 computers.
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 decompressed image it is not the
same as the original image.

This section describes the simple maintenance procedures you should
follow to replace the lamp and clean the filter.
Replacing the Lamp
After your lamp has been operating for 1500 hours (2500 hours : Eco
mode) or longer, the ÒStatusÓ light in the cabinet will go on and the
message will appear. Even though the lamp may still be working, re-
place it at 1500 (2500 hours : Eco mode) 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 electric shock.
¥ The projector will turn off and go into stand by mode after 1600 (2600
hours : Eco mode) hours of service. If this happens, be sure to replace
the lamp. If you continue to use the lamp after 1500 hours (2500 hours
: Eco mode) 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.
To replace the lamp:
1. Loosen the lamp cover screw until the screwdriver goes into a
freewheeling condition and remove the lamp cover. The lamp cover
screw is not removable.
