Operating In A High Altitude Environment; Shutting Down The Projector - Dukane 8420 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 temperature is between 0°C–35°C.
CAUTION
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 a condition.
To activate the High Altitude Mode:
1. Press MENU on the projector or MENU/EXIT
on the remote control and then press
the SYSTEM SETTING: Advanced menu is
highlighted.
2. Press to highlight High Altitude Mode and
press /
3. A confirmation message is displayed.
4. Highlight 1 and press MODE/ENTER on the projector or remote control.
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.
