The lamp in this projector operates for approximately 2,000 cumulative hours, depending on the usage environ-
ment. It is recommended that the lamp be replaced after 1,900 cumulative hours of use or when you notice a
significant deterioration of the picture and color quality. The lamp usage time can be checked with the On-screen
Display (see page 43).
