• Set [Fan mode] to [High altitude] when using the projector at altitudes approximately 5500 feet/1600 meters or higher.

Using the projector at altitudes approximately 5500 feet/1600 meters or higher without setting to [High altitude] can cause the projector to overheat and the protector could shut down. Furthermore, the projector could not turn on due to the increased temperature of the lamp after power off. If these happen, wait a couple minutes and turn on the projector.

Fan noise increases noticeably in [High altitude].

• Using the projector at altitudes less than approximately 5500 feet/1600 meters and setting to [High altitude] can cause the lamp to overcool, causing the image to flicker. Switch [Fan mode] to [Auto].
• Using the projector at altitudes approximately 5500 feet/1600 meters or higher can shorten the life of optical components such as the lamp.
