automatically turns off the power to the lamp until the projector cools.
If an over-temperature condition occurs, perform the following checks while
you allow the projector to cool:
• Verify that the room temperature is below 86 F (30 C).
• Check the intake and exhaust vents. Clear any obstruction to the air flow.
• Make sure that the fans are working. If the projector has reached an
over-temperature condition and the fans are working, you should feel a
strong flow of hot air from the left rear vent. If the fans are not working,
the projector needs service.
NOTE: If you are using the projector at a high altitude location or in a warm
room, you may want to switch to High Altitude mode (Preferences menu) to
run the fans at a higher speed (see page 2-23).
