Operating In A High Altitude Environment; Adjusting The Sound - BenQ Joybee GP2 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–30°C.
Do not use the High Altitude Mode if your altitude is between 0 m and 1499 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. Hightlight Settings and press OK to enter.
2. Go to GENERAL > High Altitude Mode and press OK.
3. Highlight On and press OK to confirm.
4. To leave the OSD, press
to go back to the home screen directly.
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.
