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 cord. Allow at least one hour for the lamp to cool before handling.
• Use the specified lamp for safety and performance.
To order the replacement lamp, specify your lamp type, NP47LP.
The replacement lamp comes with filters.
• DO NOT REMOVE ANY SCREWS except one lamp cover screw and three lamp housing 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 on the glass surface might
cause an unwanted shadow and poor picture quality.

hours after the lamp has reached the end of its life. If this happens, be sure to replace the lamp. If you continue
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.
