AUTO: The built-in fans automatically run at a variable speed according to the internal temperature.
HIGH: The built-in fans run at high speed
HIGH ALTITUDE: The built-in fans run at a 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 [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 [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 lamp 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 lamp.
• 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.
