•  Slip the filter cover back until it snaps into place.
4. Connect the supplied power cable, turn on the Main Power switch and turn on the projector.
5.  Finally, select the menu → [RESET] → [CLEAR FILTER HOURS] to reset the filter usage hours.
  (→ page 115 for resetting the filter usage time)
 Cleaning the Cabinet and the Lens
1. Turn off the projector before cleaning.
2.  Clean the cabinet periodically with a damp cloth. If heavily soiled, use a mild detergent. Never use strong 
detergents or solvents such as alcohol or thinner.
3.  Use a blower or lens paper to clean the lens, and be careful not to scratch or mar the lens.

 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 115)
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.

2. Loosen the two screws securing the lamp housing until the phillips screwdriver goes into a freewheeling 
condition. The two screws are not removable.
  Remove the lamp housing by holding it.
NOTE: There is an interlock on this case to prevent the risk of electric\
al shock. Do not attempt to circumvent this interlock.
3. Insert a new lamp housing until the lamp housing is plugged into the socket. 
CAUTION
Do not use a lamp other than the NEC replacement lamp NP06LP.
Order this from your NEC dealer.
  Secure it in place with the two screws.
 Be sure to tighten the screws.

5. Connect the supplied power cable, turn on the Main Power switch and turn on the projector.
6.  Finally, select the menu → [RESET] → [CLEAR LAMP HOURS] to reset the lamp life remaining and lamp 
usage hours.
NOTE: When you continue to use the projector for another 100 hours after the lamp has reached the end of its life, the projector 
cannot turn on and the menu is not displayed.
If this happens, press the HELP button on the remote control for 10 seco\
nds to reset the lamp clock back to zero. 
When the lamp time clock is reset to zero, the LAMP indicator goes out.
4.  Reattach the lamp cover.
  Slip the lamp cover back until it snaps into place.

8. Using Optional Lenses
Five  optional  lenses  are  available  for  the  NP3150/NP2150/NP1150.  See  the  information  described  on  this  page  to 
buy the appropriate lens for your screen size and throw distance. See page 123 for installing the lens.
 Table of Throw Distances and Screen Sizes for Optional Lenses
STANDARD (H X 1.5) - (H X 2.0) 
NP01FL (H X 0.8) 
NP03ZL (H X 1.9) - (H X 3.1) 
NP04ZL (H X 3.0) - (H X 4.8) 
NP05ZL (H X 4.7) - (H X 7.2)
NP02ZL (H X 1.2) - (H X 1.5)  
 
Example: Distance from a 100" screen with the lens Np0ZL
Referring to the diagram on page 134, “H” is 2.0 m/78.7". Therefore, the projection distances of 100 inches are from 
2.0 m/78.7" × 1.9 to 2.0 m/78.7" × 3.1 = from 3.8 m/150" to 6.2 m/244".
NOTE: Distances may vary +/-5%
For screen sizes between 30" and 500" not indicated on the above table, use formulas below.
Throw distance for Standard lens (m/inch)=H × 1.5 through H × 2.0 Distance from 0.89m to 20.83m/35.1" to 820.2"
Throw distance for NP01FL(m/inch)=H × 0.8 Distance from 0.64m to 2.5m/25.3" to 98.6"
Throw distance for NP02ZL(m/inch)=H × 1.2 through H × 1.5 Distance from 0.7m to 16.1m/27.5" to 634"
Throw distance for NP03ZL(m/inch)=H × 1.9 through H × 3.1 Distance from 1.56m to 32.15m/61.4" to 1265.6"
Throw distance for NP04ZL(m/inch)=H × 3.0 through H × 4.8 Distance from 3.6m to 49.52m/141.7" to 1949.5"
Throw distance for NP05ZL(m/inch)=H × 4.7 through H × 7.2 Distance from 5.69m to 74.36m/224.1" to 2927.5"

Remove the existing lens from the projector.
1.  Rotate  the  lens  counterclockwise  while  strongly  pushing  the 
LENS RELEASE button all the way in.
The existing lens will be disengaged.
NOTE: If the lens cannot be removed even by using the LENS RELEASE but-

 Replacing with Optional Lens
CAUTION
•  Do not give a shock or excessive load to the projector or the lens components as the projector and lens compo-
nents contain precision parts.
• When  shipping  the  projector  with  the  optional  lens,  remove  the  optional  lens  before  shipping  the  projector. The 
lens and the lens shift mechanism may encounter damage caused by improper handling during transportation.
• Before removing or installing the lens, be sure to turn off the projector, wait until the cooling fans stop, and turn 
off the main power switch.
• Do not touch the lens surface when removing or installing the lens.
• Keep fingerprints, dust or oil off the lens surface. Do not scratch the lens surface.
• Work on a level surface with a soft cloth under it to avoid scratching.
• If you remove and store the lens, attach the lens cap to the projector to keep off dust and dirt.
• Please  heed  the  following  information  if  you  own  two  or  more  NP3150/NP2150/NP1150  projectors  and  may  in-
terchange the standard lenses.
 When  replacing  the  standard  lens  (with  an  optional  lens)  and  then  re-installing  the  standard  lens  back  into  the 
projector, the standard lens must go back to its original projector from which it was removed.
 If  you  remove  the  standard  lens  from  one  NP3150/NP2150/NP1150  projector  and  re-install  it  into  another 
NP3150/NP2150/NP1150 projector, performance may be compromised.
 Be sure to use the standard lens in combination with its original factory-adjusted projector.

Over-Temperature protectionIf  the  temperature  inside  the  projector  rises  too  high,  the  over-temperature  protector  will  automatically  turn  off  the  lamp  with  the STATUS indicator blinking (2-cycle On and Off.)Should this happen, do the following:• Unplug the power cable after the cooling fans stop.• Move the projector to a cooler location if the room where you are presenting is particularly too warm.• Clean the ventilation holes if they are clogged with dust.• Wait about 60 minutes until the inside of the projector becomes cool enough.
