7. Maintenance
This section describes the simple maintenance procedures you should follow to clean the filters and replace the lamp.
 Cleaning or Replacing the Filter
The  air-filter  sponge  keeps  dust  and  dirt  from  getting  inside  the  projector  and  should  be  frequently  cleaned.  If  the 
filter is dirty or clogged, your projector may overheat.
NOTE: The message for filter cleaning will be displayed for one minute\
 when the projector is turned on or off.
To cancel the message, press any button on the projector cabinet or the r\
emote control.
CAUTION
• Turn off the projector, turn off the main power switch and unplug the projector before replacing the filter.
• Only clean the outside of the filter cover with a vacuum cleaner.
• Do not attempt to operate the projector without the filter cover.
To clean the air-filter:
Vacuum the filter-through the filter cover.
To reset the filter usage time, from the menu, select [RESET] → [CLEAR FILTER HOURS].
(→ page 133 for resetting the filter usage time)
To replace the filter (sponge):
CAUTION
• Replace both filters at the same time.
• Before replacing the filters, remove dust and dirt from the projector cabinet.
• The projector contains high-precision parts. Keep out dust and dirt during filter replacement.
• Do not wash the filter with water. Water will damage the filter membrane.
• Reattach the filter cover correctly. Failure to do so may cause projector malfunction.
Preparation: Replace the lamp before replacing the filters.
NOTE: When you replace the lamp, it is also wise to replace the filter\
. The filter comes in the same package with your replacement lamp.
1. Pull to remove the filter cover.

 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 133)
 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 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.
To replace the lamp:
Optional lamp and tools needed for replacement:
• Replacement lamp NP06LP
• Phillips screwdriver or equivalent
1. Use a Philips screwdriver to push and release the tab.
  Push and pull to remove the lamp cover.
