High Altitude

A mode for extreme environments like high altitude and high 
temperature. We recommend you use the High Altitude mode when your 
environment is higher than 3000 feet above sea level, or is hotter than 
40

℃

.

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 environments excluding the 
above, it may display auto shut-down symptoms, which is designed to 
protect your BenQ 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 environments.
