About High Altitude mode
• 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 projector could shut down. If this happens, wait a couple minutes and
turn on the projector.
• 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 internal parts
such as the lamp.
