Replacing the projection lamp
The lamp hour timer in the About menu counts the number of hours the
lamp has been in use. When the specified end of the lamp’s life is reached,
the message “Replace lamp” briefly appears on the screen at each startup
and in the Interactive Display. You can order new lamp modules from your
dealer. See “Accessories” on page 41 for information.
