» 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. After replacing the lamp, be sure to clear the lamp hour meter. See
page 47.
CAUTION
• DO NOT TOUCH THE LAMP immediately after it has been used. It will be extremely hot. Turn the projector off,
wait 30 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 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 standby 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.

The projector will turn off and go into standby mode after 3100 (up to 4100 hours in Eco mode) hours of service.
