This section describes the simple maintenance procedures you should follow
to replace the lamp, clean or replace the filter, and replace the batteries in the
remote control.
Replacing The Lamp
After your lamp has been operating for 2000 hours or longer, the red
“status” light in the cabinet will go on and the lamp icon will appear on
the above right of the screen whenever the projector is turned on. The
lamp icon remains on after 2100 hours of service. Even though the lamp
may still be working, replace it at 2000 hours to maintain optimal projec-
tor performance.
CAUTION
• DO NOT TOUCH THE LAMP immediately after it has been used. It will be
extremely hot. Allow at least one hour for the lamp to cool before
handling.
• DO NOT REMOVE ANY SCREWS except the lamp cover set screw and
two lamp case screws. You could receive an electric shock.
• Do not touch the front surface portion of the replacement lamp body in
which glass is used.
Touching the glass portion or bulb tip may result in a drop of the
brightness or shortened bulb life.
• Turn off the main power to the projector and disconnect the power cord.
Allow at least one hour for the lamp to cool.
• If you continue to use the lamp after 2000 hours 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.
To replace the lamp:
1. Loosen the single captive screw that secures the lamp housing cover and
remove the cover.
2. Loosen the two captive screws securing the lamp case.
3. Remove the lamp by pulling out the complete assembly.
4. Install a new lamp case assembly and secure it in place with the two
captive screws.
CAUTION: Do not use a lamp other than the NEC replacement lamp.
Order this from your NEC dealer using your projector's model number.
5. Reattach the lamp housing cover and tighten the single captive screw.
6. After you install a new lamp, select [Display] from the main menu, and press
the ENTER button. Then press the remote ▲/▼ button to select [Lamp
Usage], then press the NORMAL button to display the Reset menu. Press the
remote ▲/▼ button to select [Yes] and press the ENTER button.
This resets the lamp clock back to zero.
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.

To view the lamp usage time:

appear.
To reset the lamp clock back to zero:
1. Select [Display] from the main menu, and press the ENTER button.
2. Press the remote ▲/▼ button to select [Lamp Usage], then press the
NORMAL button.
