34 Using the projector
English
Operating in a high altitude environment
We recommend that you activate High Altitude Mode when your environment is higher than 1500 meters
(around 4920 feet) above sea level, or whenever the projector will be used for extended periods of time
(>10 hours) without shutdown.
To activate High Altitude Mode:
1. Press MENU and then press / until the Advanced Setup menu is
highlighted.
2. Press to highlight High Altitude Mode.
3. Press / to select On. A confirmation message displays.
4. 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. Howeve r, this is
not to state that this projector can operate under any and all harsh or
extreme conditions.
High Altitude Mode is used when the
environment is higher than 1500m.
