USER GUIDELCD PROJECTOR22 9 FEATURES The LCD projector has a variety of different features implemented. This chapter explains each feature in detail. 9.1.1 INTELLIGENT SAFECOOL SYSTEM The fan operates as long as the LCD projector is switched on. Provided that the power cord is connected, the fan continues to run for 2 minutes even after the unit has been switched off. This ensures a continuous protection against high temperature inside the projector. The cooling system is designed to minimize stray light and noise. If the air flow is blocked, a temperature safety fuse will automatically shut off the projector to protect it from overheating. 9.1.2 SET-UP MEMORY The user controlled set-up, that usually is done when the projector 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. The memory can store 40 different sources/modes. Some sources are predefined, while the remaining are available for customer set-up. See the Technical Data section for compatibility. Custom sources are added to the memory only if their sync pattern differs from any of the previous selections. The projector automatically selects a new memory location. Most settings are stored individually for each mode, including contrast, brightness, tune etc. See the remote control table in the Remote Control section. OSD SYSTEM The OSD (On Screen Display) system echoes on screen your keypad or remote control actions. The OSD may be switched off and on by pressing the OSD key on the remote control.
USER GUIDELCD PROJECTOR23 9.1.3 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. Use the CONTR keys on the remote control (RC) to adjust the contrast. Also see Brightness. The contrast setting is stored individually for each mode. 9.1.4 BRIGHTNESS The brightness is the amount of white in an image. The brightness is adjusted to the ambient lighting conditions. Usually, a bright, low contrast image is preferred. Use the BRIGHT keys to adjust brightness. See also Contrast. The brightness setting is stored individually for each source. 9.1.5 TUNE This feature enables a stable image. An unstable image can be seen as sideways instability or “swimming”. Press TUNE until a stable image is achieved. The setting is stored individually for each source. Observe that TUNE only works provided the FREQUENCY setting is correct. 9.1.6 ON/OFF This switch controls the operation of the projector. When switched on, all functions are active. When switched off, the fan is still operating, but the image is turned off. If the unit is left off for more than 5 minutes, the lamp is also turned off and after another 2 minutes the fan terminates. The ON/OFF switch is a toggle key.After the lamp is turned off, the unit can only be turned on again after a safety delay of 60 seconds. If the projector is turned on during the safety delay period, the On/Off indicator will blink slowly until the 60 seconds have passed and the lamp is turned on.9.1.7 RESET This feature enables standard settings of most controls. RESET will only reset the active mode.A fundamental master reset may be performed by pressing all four top panel keys simultaneously. 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.
USER GUIDELCD PROJECTOR24 9.1.8 SOURCE 1/2/3 These keys select between the 3 analog RGB inputs. Only one input can be active at a time. All three inputs have the same properties and can be used for either computer/workstation or RGB video sources. The Projector defaults to input source 1 at power on. If no signal is connected, the message NO SOURCE appears on the screen. 9.1.9 FREEZE Press the FREEZE button on the RC to lock the image displayed. This feature is useful if you want to make changes locally on your computer that should not be presented to the audience. Press FREEZE once more to resume on-line operation. Any other key pressed will also release FREEZE. 9.1.10 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 blank when activated. Any key pressed will release BLANK. 9.1.11 REAR The projector 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. A special transmissive screen is needed. A typical application is in exhibitions. REAR is a toggle function on the RC. 9.1.12 FREQUENCY This setting is provided for adaptation to Workstations and special graphics adapters that are not recognized automatically by the projector. An incorrect frequency setting can be seen as an image to wide or too narrow, combined with vertical, unstable bands. To better see this effect, fill a large portion of your screen with a 50% grey pattern (alternating black and white pixels). Make sure that Expansion/Compression is deactivated i.e. your image is viewed in default 1:1 mode. This is done by pressing the SCALE key on the remote control. Press the FREQUENCY keys left or right to adjust the setting until all vertical banding disappears. The final setting is stored individually for each source. 9.1.13 POSITION Due to minor variations in graphics adapters, the horizontal and vertical position may need adjustment. Press POSITION, then use the cursor keys to position the image. The position is stored individually for each mode.
USER GUIDELCD PROJECTOR25 9.1.14 SCALE Scaling is applicable to images that have a lower or higher resolution than the 1024x768 active LCD area. Pressing SCALE toggles between direct mapping (1:1) and compression of oversized images (1280x1024 or 1152x900), or expansion of undersized images (640x480 or 800x600). Default power on setting for oversized images is to view the image in 1:1, undersized images are expanded. 9.1.15 PAN Panning is only applicable with oversized images (1280x1024 and 1152x900) when displayed in 1:1 (not compressed, see SCALE). Press PAN , then use the cursor keys on the remote control to perform the actual panning.Observe that the mouse cannot be controlled from the remote while PAN is activated.The PAN function is automatically deselected after 5 seconds of no key activity. OSD The OSD (On Screen Display) is switched on or off with this toggle key. 9.1.16 MOUSE The BatMouse remote control (RC) employs a unique mouse functionality that enables full mouse control of your PC, PS/2 or Macintosh computer. By default, the cursor keys of the remote control emulate the mouse movement. The LEFT and RIGHT keys emulate the left and right keys on a standard two-key mouse (for Macintosh, only the DRAG key is used). The DRAG key is used to emulate the click-and-hold action. To move an object, position the mouse cursor, press DRAG to tag the object, position the object as desired using the cursor keys, then press DRAG again to release the object. DRAG is automatically released after 5 seconds of no key activity.The mouse control can only be used with computers that fully support PC, PS/2 or MAC ADB mouse - electrically and functionally.
