Replacing the Lamp and the Cooling Pump

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. (→ page

CAUTION

• The optional lamp comes with the cooling pump.

After replacing the lamp, be sure to replace the cooling pump, too.

• 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  nger prints off the glass surface on the lamp housing. Leaving  nger 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 ser-

vice. 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.
