Resetting the lamp hours
After you replace the lamp module, you need to access the projector service menu and reset the lamp
hours. To prevent accidental errors, only a system administrator should perform this procedure.
N O T E
Always reset the lamp hours after you replace the lamp, because lamp service reminders are based
on the current hours of use.

other settings can damage or affect the operation of your projector and may invalidate your

projector has been in use.
