Replacing the Projection Lamp

The average life of the lamp is 2,000 hours. When the lamp has been in use for 1,500 hours, the lamp LED alternately blinks green and red. After 1,900 hours, the word “LAMP!” appears on the screen for one minute. After 2,000 hours, the lamp shuts off automatically. The projector cannot be used until you replace the lamp and reset the lamp timer. You can order new lamp modules from your InFocus dealer. See “Accessories” on page 40 for infor- mation.

WARNING: To avoid burns, allow the projector to cool for at least 60 minutes before you open the lamp module door. Never extract the lamp module while the lamp is operating.

CAUTION: Never operate the projector with the lamp door open or removed. This disrupts the air flow and causes the projector to overheat.
