BenQ PB2240 user manual High Altitude Mode

High Altitude Mode

A mode for extreme environments like high altitude and high tempera- ture. We recommend you use the High Altitude Mode when your environ-

ment is higher than 3000 feet, or is hotter than 40℃.

Operation under "High Altitude Mode" may cause a higher decibel oper- ating noise level because of increased fan speed necessary to improve over- all 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 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.
