See the technical data section for pinouts of the various connectors. POWER MOUSE COMPUTER Do not connect any other devices with similar plugs to the connectors of the LCD panel, as this voids any warranty and may cause permanent damage to the device. CONNECTOR POWER MOUSE COMPUTER FUNCTION Low voltage power supply Universal mouse connector Analog RGB video input 12 USER GUIDE LCD PANEL 7 FEATURES The LCD panel has a variety of different features implemented. 7. 1. 1 INTELLIGENT SAFECOOL SYSTEM The fan operation is controlled by the overhead projector light (OHP). This safety feature ensures that the fan is always operating as long as the OHP is turned on. When the OHP is turned off, the fan automatically stops to minimize noise. The power supply must be attached to the panel for the fan to work properly. 7. 1. 2 SET-UP MEMORY The user controlled set-up, that usually is done when the panel is connected to a new computer, is automatically memorized for future use. The set-up information is stored in a non-volatile memory approximately 5 seconds after the last key is pressed. Several sources are predefined, while the remaining are available for customer set-up of sources. Custom sources are stored only if their sync pattern differs from any of the previous selections. Most settings are stored individually for each mode, including contrast, brightness, tune etc. 7. 1. 3 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 contrast setting is stored individually for each mode. 13 USER GUIDE LCD PANEL 7. 1. 4 BRIGHTNESS The brightness is the amount of white in an image. An unstable image can be seen as sideways instability or ` swimming' Press TUNE until a stable image is . When switched off, the automatic fan control is still operating, but the image is turned white. A fundamental master reset may be performed by pressing all four front panel keys simultaneously for approx. All settings will return to factory defaults, so do not perform a master reset unless it is really required. This operation will also erase all custom sources and modes that have been memorized. [. . . ] 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. [. . . ]
