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 temperature is between 5°C–25°C.
CAUTION
Do not use the High Altitude Mode if your altitude is between 0 m and 1499 m and temperature
is between 5°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.
Open the OSD menu and go to the
INSTALLATION > High Altitude Mode
menu.
2.
Press Enter and press
A confirmation message is displayed.
3.
Highlight Yes and press 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.
