PLEASE REPLACE THE LAMP AND FILTER.” will appear (*). Even though the lamp 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. (→ page 102) 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. Replacement lamp: NP33LP: UM351W/UM361X NP32LP: UM301W/UM301X The replacement lamp comes with filters. While the filters attached to the projector at the time of purchase are made of dark sponge material, the filters included with the optional lamp are made of non-woven white material. There is no difference in performance between these two types. • DO NOT REMOVE ANY SCREWS except one lamp cover screw and two 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. • 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 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.
