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, go to Control > High Altitude Mode, select On

by pressing Left/ Right on the projector or remote control. A confirmation message displays. Press AUTO.

We recommend you use the High Altitude Mode by selecting On

when your environment is higher than 3000 feet, or is hotter than 40°C.

Next time you turn on the projector, it will show a message pictured below as a reminder during the start-up.

Current Status

High Altitude Mode On

This mode is used for protecting projector from extreme environment and may cause high

fan speed.

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.

Personalizing the projector menu display

The On-Screen Display (OSD) menus can be set according to your preferences. The following settings do not affect the projection settings, operation, or performance.

•OSD Time in the Control > OSD menu sets the length of time the OSD will remain active after your last button press. The time length ranges from 5 to 60 seconds in 5- second increments.

•Language in the Control menu sets your familiar language for the OSD menus. Use

Left/ Right on the projector or remote control to select your language.

•User Logo in the Control > Setup menu allows you to set a preferred logo screen to be displayed during projector start-up.
