6. MAINTENANCE
This section describes the simple maintenance procedures you should follow to replace the lamp and clean the
projector cabinet.
Replacing the Lamp
After your lamp has been operating for 2000 hours (up to 3000 hours in Eco mode) or longer, the lamp indicator
in the cabinet will blink red and the message "The lamp has reached the end of its usable life. Please replace the
lamp." will appear. Even though the lamp may still be working, replace it at 2000 (up to 3000 hours in Eco mode)
hours to maintain optimal projector performance.
CAUTION
DO NOT TOUCH THE LAMP immediately after it has been used. It will be extremely hot. Turn the projec-
tor off, wait 60 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 sur-
face might cause an unwanted shadow and poor picture quality.
The projector will turn off and go into stand by mode after 2100 (up to 3100 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 3000 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:
Preparation:
Be sure to insert the included spacer between the rear foot and the projector’s bottom to prevent the projector
from accidentally tilting when inserting the lamp house.
Spacer
Remove the spacer after replacing the lamp.
