Replacing The Projection Lamp - InFocus LP 730 User Manual

Replacing the Projection Lamp

The lamp hour counter on the status bar at the top of the menus
counts the number of hours the lamp has been in use. After 2000
hours of use, the lamp monitor LED, marked
projector near the keypad, lights. After 2050 hours, the lamp
switches off completely and must be replaced. You can order new
lamp modules from your In Focus dealer. See "Accessories" on
page 51 for information.
