InFocus LP540 Replacement Instructions

Replacing the projection lamp

The lamp hour timer in the About menu counts the number of hours the
lamp has been in use. Fifty hours before the specified end of the lamp's life,
the message "Replace lamp" briefly appears on the screen at each startup
and in the Interactive Display. After 50 additional hours, the lamp will no
longer light. You can order new lamp modules from your dealer. See
"Accessories" on page 41 for information.
