￿Replacing the Lamp

After your lamp has been operating for 2000 hours (up to 2500 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 2500 hours in Eco mode) hours to maintain optimal projector performance. After replacing the lamp, be sure to clear the lamp hour meter. (page 45)

CAUTION

DO NOT TOUCH THE LAMP immediately after it has been used. It will be extremely hot. Turn the projector off 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 2600 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 2500 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 replace- ment.
