Operating in a high altitude environment

We recommend 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. However, this is not to state that this projector can operate under any and all harsh or extreme conditions.

Hiding the picture

In order to draw the audience's full attention to the presenter, you can use BLANK to hide the screen picture. The word 'BLANK' appears in the lower right corner of the screen while the picture is hidden. When this function is activated with an audio input connected, the audio can still be heard.

You can set a time length in the System Setup > Blank Timer menu to restore the picture after a period of time when there is no action taken on the projector or remote control. The length of time can be set from 5 to 30 minutes in 5-minute increments.

If the preset time spans are not suitable for your personation, select Disable.

No matter Blank Timer is activated or disabled, you can press any key (except LASER) anytime you want to restore the picture.
