Replacing the Lamp and the Cooling Pump

may still be working, replace the lamp to maintain the optimal projector performance. After replacing the lamp, be
sure to clear the lamp hour meter. (

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,

wait for the cooling fans to stop and then disconnect the power cable. Allow at least one hour for the lamp to
cool before handling.

• DO NOT REMOVE ANY SCREWS except one lamp cover screw and two lamp housing screws. You could re-

ceive 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 when you continue to use the projector for another 100

hours after the lamp has reached the end of its life. If this happens, be sure to replace the lamp. If you con-
tinue to use the lamp after the lamp reaches the end of its life, 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.
