This section describes the simple maintenance procedures you should foll\
ow 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.

 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

ojector 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 [ R ESET] → [C LEAR  F ILTER  H OURS].

 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 121)
 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 re
-
ceive 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 600 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.
