Switching input signal

The projector can be connected to multiple devices at the same time. However, it can only display one at a time. To cycle through the available input sources, press the Source (or SOURCE/WIRELESS) button. A source selection menu will display at the center of the screen after you press the button.

The brightness level of the projected image will change accordingly when you switch between different input signals. Data (graphic) "PC" presentations using mostly static images are generally brighter than "Video" using mostly moving images (movies).

The input type affects the options available for the Application Mode. See "Selecting an application mode" on page 26 for details.

Hiding the image

In order to draw the audience’s full attention to the presenter, you can press the Blank (or BLANK /

5Up) button to hide the screen image. Press the button again to restore the image. The word “BLANK” appears at the bottom right corner of the screen while the image is hidden.

You can set the blank time in the Advance --

> Blank Time menu to let the projector return the image automatically after a period of time when there is no action taken on the blank screen.

Do not block the projection lens from projecting as this could cause the blocking object to become heated and deformed or even cause a fire.
