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
/
until the SYSTEM SETUP: Advanced menu
is highlighted.
2.
Press
to
highlight
High Altitude Mode and press
/
to select On. A
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.
