Operating in a high altitude environment
We recommend you use the
High Altitude Mode
when your environment is 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

SYSTEM SETUP: Advanced
menu is highlighted.

High Altitude Mode

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.
