Replacing the projection lamp
The lamp hour timer in the About menu counts the number of hours the
lamp has been in use. After 1980 hours, the message “Change lamp” briefly
appears on the screen at each startup. To maintain optimal video perfor-
mance, we recommend changing the lamp after 2000 hours, depending on
usage. You can order new lamp modules from your dealer. See “Accesso-
ries” on page 32 for information.
