of time (>10 hours) without shutdown.

Operation under
High Altitude Mode
may cause a higher decibel operating noise level because of
increased fan speed necessary to improve overall system cooling and performance.
If you use this projector under other extreme conditions excluding the above, it may display auto shut-
down symptoms, which is designed to protect your projector from over-heating. In cases like this, you
should switch to
High Altitude Mode
to solve these symptoms. However, this is not to state that this
projector can operate under any and all harsh or extreme conditions.
