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.
TIP:
• When [HIGH ALTITUDE] is selected for [FAN MODE], a symbol icon will be displayed at the bottom of the menu.
