4. MAINTENANCE
This section describes the simple maintenance procedures you should
follow to replace the lamp, clean the filter, and replace the batteries
in the remote control.
Replacing the Lamp
After your lamp has been operating for 2000 hours (up to 3000 hours
in Eco mode) or longer, the “Status” light in the cabinet will go on
and the message will appear. Even though the lamp may still be work-
ing, replace it at 2000 (up to 3000 hours in Eco mode) hours to main-
tain optimal projector performance.
CAUTION
• DO NOT TOUCH THE LAMP immediately after it has been
used. It will be extremely hot. Turn the projector off, wait 30
seconds, and then disconnect the power cable. Allow at least
one hour for the lamp to cool before handling.
• DO NOT REMOVE ANY SCREWS except the lamp cover
screw and two lamp case screws. You could receive an electric
shock.
•
The projector will turn off and go into stand by mode after 2100
(up to 3150 hours in Eco mode) hours of service. If this happens,
be sure to replace the lamp. If you continue to use the lamp after
2000 hours (up to 3150 hours in Eco mode) 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 lamp cover screw until the screwdriver goes into a
freewheeling condition and remove the lamp cover. The lamp cover
screw is not removable.

electrical shock. Do not attempt to circumvent this interlock.
