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� (→ page 70)

• Set [FAN MODE] to other than [HIGH ALTITUDE] mode when using the projector at altitudes approximately 5500 feet/1600
meters or lower� 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]� (→ page 70)
