Selecting Fan Mode [FAN MODE]
Fan Mode is used to set the speed of the internal cooling fan.
MODE �������������������� Select one among four modes: AUTO, NORMAL, HIGH, and HIGH ALTITUDE�
AUTO: The built-in fans automatically run at variable speed according to the detected temperature and
atmospheric pressure by the built-in sensor�
NORMAL: The built-in fans run at the appropriate speed based on the detection by the built-in temperature
sensor�
HIGH: The built-in fans run at high speed
HIGH ALTITUDE: The built-in fans run at high speed� Select this option when using the projector at altitudes
approximately 5500 feet/1700 meters or higher�
NOTE:
• Make sure the speed is set to [HIGH] when you are using this device continuously for several days.
• Set [FAN MODE] to [AUTO] or [HIGH ALTITUDE] when using the projector at altitudes approximately 5500 feet/1700 meters or
higher.
• Using the projector at altitudes approximately 5500 feet/1700 meters or higher without setting to [AUTO] or [HIGH ALTITUDE]
can cause the projector to overheat and the protector 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/1700 meters and setting to [HIGH ALTITUDE] can cause the
projector to overcool, causing the image to flicker. Switch [FAN MODE] to [AUTO].
• Using the projector at altitudes approximately 5500 feet/1700 meters or higher can shorten the life of optical components such
as the light source.
• Your setting will not be affected even when [RESET] is done from the menu.
