Operating In A High Altitude Environment; Adjusting The Sound; Adjusting The Sound Level - BenQ MX511 User Manual

Operating in a high altitude environment

We recommend you use the High Altitude Mode when your environment is between 1500 m
–3000 m above sea level, and ambient temperature is between 0°C–35°C.
Do not use the High Altitude Mode if your altitude is between 0 m and 1500 m and ambient
temperature is between 0°C and 35°C. The projector will be over cooled, if you turn the mode
on under such a condition.
To activate the High Altitude Mode:
1. Press Menu/Exit and then press
highlighted.
2. Press
confirmation message displays.
3. Highlight Yes and press Mode/Enter.
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.
