 Replacing the Lamp
After your lamp has been operating for 2000 hours (up to 3000 hours in Eco mode) or longer, the LAMP indicator in the
cabinet will blink red and the message will appear. Even though the lamp may still be working, replace it at 2000 (up to
3000 hours in Eco mode) hours to maintain optimal projector performance. After replacing the lamp, be sure to clear
the lamp hour meter. See page 
50 .
CAUTION
• DO NOT TOUCH THE LAMP immediately after it has been used. It will be extremely hot. Turn the projector off,wait 30 seconds, turn off the main power switch and then disconnect the power cable. Allow at least one hour
for the lamp to cool before handling.
• DO NOT REMOVE ANY SCREWS except two lamp case screws. You could receive an electric shock.
• Do not break the glass on the lamp housing. Keep finger prints off the glass surface on the lamp housing. Leaving finger prints in the glass surface might
cause an unwanted shadow and poor picture quality.
• The projector will turn off and go into stand by mode after 2100 (up to 3100 hours in Eco mode) hours of service. If this happens, be sure to replace the lamp. If you continue to use the lamp after 2000 hours (up to
3000 hours in 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.

7. Appendix
If there is no picture, or the picture is not displayed correctly.
• Power on process for the projector and the PC.
Be sure to connect the RGB cable between the projector and the computer before turning on the computer.
There are some notebook PCs, which do not output signal unless there is a projector or monitor conn\
ected first.
NOTE: You can check the horizontal frequency of the current signal in the projector’s menu under Information.  If it reads
“0kHz”, this means there is no signal being output from the computer. See page  49  or go to next step.
•Enabling the computer’s external display.
Displaying an image on the notebook PC’s screen does not necessarily mean it outputs a signal to the projec-
tor.  When using a PC compatible laptop, a combination of function keys will enable/disable the external display.
Usually, the combination of the ‘Fn” key along with one of the 12 function keys gets the external display to come
on or off.  For example, NEC laptops use Fn + F3, while Dell laptops use Fn + F8 key combinations to toggle
through external display selections.
• Non-standard signal output from the computer
If the output signal from a notebook PC is not an industry standard, the\
 projected image may not be displayed
correctly. Should this happen, deactivate the notebook PC’s LCD screen when the projector display is in use.
Each notebook PC has a different way of deactivate/reactivate the local LCD screens as described in the
previous step. Refer to your computer’s documentation for detailed information.
• Image displayed is incorrect when using a Macintosh
When using a Macintosh with the projector, set the DIPswitch of the Mac adapter (not supplied with the projec-
tor) according to your resolution. After setting, restart your Macintosh for the changes to take affect.
For setting display modes other than those supported by your Macintosh and the projector, changing the DIP
switch on a Mac adapter may bounce an image slightly or may display noth\
ing. Should this happen, set the DIP
s witch to the 13” fixed mode and then restart your Macintosh. After that, restore the DIP switches to a
displayable mode and then restart the Macintosh again.
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.
• Mirroring on a PowerBook
* When using the projector with a Macintosh PowerBook, output may not be set to 1024 x 768 unless “mirror-
ing” is off on your PowerBook. Refer to owner’s manual supplied with your Macintosh computer for mirroring.
• Folders or icons are hidden on the Macintosh screen
Folders or icons may not be seen on the screen. Should this happen, select [View]  → [Arrange] from the Apple
menu and arrange icons.
