4. MAINTENANCE
This section describes the simple maintenance procedures you should
follow to replace the lamp.
Replacing the Lamp
After your lamp has been operating for 1000 hours (up to 1500 hours
: Eco mode) or longer, the “Status” indicator in the cabinet will go
on and the message will appear. Even though the lamp may still be
working, replace it at 1000 hours (up to 1500 hours : Eco mode) to
maintain 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 90
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 three lamp case screws. You could receive an elec-
tric shock.
• The projector will turn off and go into stand by mode after 1100
hours (up to 1600 hours : Eco mode) of service. If this happens,
be sure to replace the lamp. If you continue to use the lamp after
1000 hours (up to 1500 hours : 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.
2 Loosen the three screws securing the lamp housing until the screw-
driver goes into a freewheeling condition. The three screws are
not removable.
4 Insert a new lamp housing until the lamp housing is plugged into
the socket.
