 Replacing the Lamp
When the lamp reaches the end of its life, the LAMP indicator in the cabinet will blink red. Even though the lamp may 
still be working, replace the lamp to maintain the optimal projector performance. After replacing the lamp, be sure to 
clear the lamp hour meter. (→ page 69)
 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 one lamp cover screw and two lamp housing 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 on the glass surface might cause 
an unwanted shadow and poor picture quality.
•  The projector will turn off and go into standby mode when you continue to use the projector for another 100 hours 
after the lamp has reached the end of its life. If this happens, be sure to replace the lamp. If you continue to use 
the lamp after the lamp reaches the end of its life, 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.

•  Be sure to connect the projector and notebook PC while the projector is in standby mode and before turning 
on the power to the notebook PC.In  most  cases  the  output  signal  from  the  notebook  PC  is  not  turned  on  unless  connected  to  the  projector before being powered up.
* If the screen goes blank while using your remote control, it may be the result of the computer’s screen-saver 
or power management software.
•  See also the next page.
•  Check if the projector is in the Forced ECO mode because of too high ambient temperature. If this is the case, 
lower the internal temperature of the projector by selecting [HIGH] for \
[FAN MODE]. (→ page 63)
•  Check if an appropriate color is selected in [WALL COLOR]. If so, select an appropriate option. (

•  Condensation may form on the lens if the projector is cold, brought into a warm place and is then turned on. 
Should this happen, let the projector stand until there is no condensati\
on on the lens.
•  
Set [FAN MODE] to other than [HIGH ALTITUDE] mode when using the projector at altitudes approximately 5500 feet/1600 meters or lower. Using the projector at altitudes less than approximately 5500 feet/1600 meters and setting to [HIGH ALTITUDE] can cause the lamp to overcool, causing the image to flicker. Switch [FAN MODE] to [AUTO]. (→ page 63)

If there s no pcture, or the pcture s not dsplayed correctly.
• Power on process for the projector and the PC.
  Be sure to connect the projector and notebook PC while the projector is in standby mode and before turning on 
the power to the notebook PC.
  In most cases the output signal from the notebook PC is not turned on unless connected to the projector before 
being powered up.
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. (→ page 68 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 projector.  
When using a PC compatible laptop, a combination of function keys will enable/disable the external display.  Usu-
ally, 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 projector) 
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 nothing. Should this happen, set the DIP switch 
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 “mirroring” 
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.

***  What is HDCP/HDCP technology?
  HDCP is an acronym for High-bandwidth Digital Content Protection. High bandwidth Digital Content 
Protection (HDCP) is a system for preventing illegal copying of video data sent over a Digital Visual Interface (DVI).
  If  you  are  unable  to  view  material  via  the  DVI  input,  this  does  not  necessarily  mean  the  projector 
is not functioning properly. With the implementation of HDCP, there may be cases in which certain content is protected with HDCP and might not be displayed due to the decision/intention of the HDCP community (Digital Content Protection, LLC).
****  An image with higher or lower resolution than the projector’s native resolution (NP600/NP500/NP400: 
1024  768 / NP500W: 1280  800) will be displayed with Advanced AccuBlend.
