Replacing the Lamp
After your lamp has been operating for 2000 hours (up to 4000 hours : Eco mode) or longer, the "Lamp" indicator in the
cabinet will blink red and the message will appear. Even though the lamp may still be working, replace it at 2000 hours
(up to 4000 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, 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 the lamp cover screw and two lamp case 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 in the glass surface might
cause an unwanted shadow and poor picture quality.
The projector will turn off and go into stand by mode after 2100 hours (up to 4100 hours : Eco mode) of service.
If this happens, be sure to replace the lamp. If you continue to use the lamp after 2000 hours (up to 4000 hours :
Eco mode) of use, the lamp bulb may shatter, and pieces of glass may be scattered in the lamp housing. 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 two screws securing the lamp housing until the screwdriver goes into a freewheeling
condition. The two screws are not removable.
