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 0°C–35°C.
Do not use the High Altitude Mode if your altitude is between 0 m and 1500 m and temperature
is between 0°C and 35°C. The projector will be over cooled, if you turn the mode on under
such condition.
To activate the High Altitude Mode, go to SYSTEM SETUP: Advanced > High Altitude
Mode, select On by pressing Left/ Right on the projector or remote control. A
confirmation message displays. 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.
We recommend you use the High
Altitude Mode by selecting it whenever
your environment is higher than 1500 m.
Do you want to turn the High Altitude
Mode on?
