Operating in a high altitude environment
We recommend you use the High Altitude Mode when your environment is higher than 3000 feet above sea level,
or is hotter than 40°C, or whenever the projector will be used for extended periods of time (>10 hours) without
shutdown.
To activate the High Altitude Mode, select On by pressing Left/ Rig ht on the projector or remote control. A
confirmation message displays. Press AUTO.
Next time you turn on the projector, it will show a message pictured below as a reminder during the start-up.
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.
