tionsÓ of the menu, any given slide will start to play automati-
cally. You can also specify Auto Play Interval between 5 and 300

Switching to Slides Directly from Other Input Modes
With this function it is possible to switch directly to a slide when the
picture of a VCR or computer is being projected.
Example:
When conducting presentations using a combination of slides and
moving pictures from a VCR, etc., it is possible to switch from a PC
Card Viewer slide to the video picture then back to the PC Card  Viewer
slide simply by using the Source button.
NOTE: Even if you switch the current PC Card Viewer source to another source,
the current slide is retained. When you return back to the PC Card Viewer, you
will get the slide that has been retained.
NOTE: The CompactFlash card editing operation cannot be performed from
the projector.  Do so using the PC Card Viewer software.

* Press the eject button to eject the card.
1. Project the image you wish to store on the projector.
2. Select the ÒCaptureÓ from the Tools menu.
NOTE:
¥ File size of the captured image varies depending on the resolution of an
input signal.
¥ Since an image data is compressed with the JPEG format, the image is
slightly degraded.
NOTE: An hourglass indicating that an image is being captured appears on the
projectors display.  Do not eject the CompactFlash card or turn off the
projectors power while this icon is displayed.  Doing so will damage the
CompactFlash card data.
If the CompactFlash card data is damaged, use a computer to repair the data.
NOTE: The folder in the right bottom is always a folder exclusively for cap-
tured images.  To display the list of folders when there are 13 or more indexes
stored on the CompactFlash card, select Edit index from the PC Card Viewer
softwares File menu and move the index you want to display to within 12
indexes from the top of the folder index.  For details on indexes, refer to the

lution cannot be displayed correctly. 
						

							EÐ50 Deleting Captured Images
Uninstalling the PC Card Viewer Software
Even if you do now know the PC Card Viewer softwares file names
or where they are stored, the PC Card Viewer software files can be
easily removed from the system using the Install/Uninstall Applica-
tions control panel in Windows.  (Normally there is no need to per-
form this operation.)
Uninstalling the software
Use the procedure described below to uninstall the PC Card Viewer

Digital images can be played with the PC Card Viewer if the follow-
ing conditions are met:
¥ If the image can be stored on an MS-DOS format CompactFlash
card
¥ If the image can be stored in a format supported by the PC Card
Viewer.
With the PC Card Viewer, images on the card are searched for in
directories and images in JPEG or BMP format are recognized
as slides.
Searchable directories are directories within two steps from the
root directory, and searchable images are images within the first
12 files in the directory.  Only file and slide switching are pos-
sible.
NOTE: The maximum number of images recognized as slides within one di-
rectory is 128.
2. In the Control Panels dialog box, double-click on Add/Remove
Programs.
3. In the Add/Remove Programs Properties dialog box, click the

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.
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 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.
Replacing the Lamp
After your lamp has been operating for 1000 hours 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 1000 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 90
seconds, 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 1100
hours of service. If this happens, be sure to replace the lamp. If
you continue to use the lamp after 1000 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.
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.
2 Loosen the three screws securing the lamp housing until the screw-
driver goes into a freewheeling condition. The three screws are
not removable.4 Insert a new lamp housing until the lamp housing is plugged into
the socket.
