[. . . ] The custom sources will be stored in new locations if their sync pattern is different from those predefined. If the set-up is only a variety of a standard source (same sync pattern) the old setting will be changed and stored in the existing location. Most settings are stored individually for each source, including contrast, brightness, tune etc. CONTRAST The contrast of an image is defined as the relation between dark and light colors. An image of high contrast is often regarded as 'hard', as compared to the 'soft' feeling of a low contrast image. Low contrast is recommended for long term viewing, while high contrast is used to enhance details. The brightness setting is stored individually for each source. 11 USER GUIDE LCD PANEL TINT The tinting refers to the color balance of an image. You may actively want to make an image warmer (more reddish) or colder (more bluish), or the colors of the graphic interface in your computer could be unbalanced and in need of adjustment. BLANK Use the BLANK key on the RC, if you temporarily want to suspend the display of images. The BLANK key is a toggle function, and the screen goes white when activated. INVERSE This feature inverts the black-and-white contents of an image, retaining all other colors unchanged. This feature is also called 'night vision', because a black or dark grey color is turned light. The inverse function is most valuable in text applications, and rarely used with graphics. REAR The panel can be set to project a mirrored image for rear projection. Rear projection is used when only the actual image is displayed, without showing the projection equipment. PALETTE Usually, the palette is set to display the maximum number of colors available, regardless of application. By pressing the PALETTE switch on the RC, the color palette is cycled between 512, 4096 and 2. 1 million colors. The ON/OFF switch is a toggle key. 12 USER GUIDE LCD PANEL MAC The MACII series of computers are equipped with slightly different graphic interfaces that need manual setup on the RC to work correctly. Pressing the MAC key toggles between the MACII LC 640x480 mode and the standard 640x480 mode. An erroneous mode will typically be seen as an image too wide or too narrow, as well as vertical unstable lines. TEXT The TEXT key is used to toggle between the MCGA graphics mode and the text mode, as this is not automatically detected. This feature is very useful, as it enables a correctly set text image without any loss of information. [. . . ] However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures : Reorient the receiving antenna. Plug the equipment to a different outlet so that equipment and receiver are on different branch circuits. You may require the following booklet from the Federal Communications Commission (FCC) : "How to identify and resolve radio and TV interference problems", available from the U. S. [. . . ]
