5 SETTING UP THE LCD PANEL
Switch off all equipment before connecting the components. Be aware of static electricity that may build up, especially in the dry season and when operating on synthetic carpets. Discharge any static electricity by touching a metallic surface before you start.
Place the LCD panel on top of a transmissive overhead projector (OHP). Select a high intensity type projector, for instance 400W. Best results are obtained in a dimmed room with no direct sunlight shining in. Using the LCD panel on some metal halide OHP’s may cause visible flicker. This will not harm the LCD panel.
The following are guidelines for first time set-up:
• Connect the cables and power supply as described in the rear foldout
page (see Connection Layout).
• Attach power to the LCD panel, turn the overhead projector and
computer on.
Do not switch on the OHP unless the LCD panel is powered, as this may cause permanent damage.
If you are going to use a mouse, make sure to power the LCD panel first. For more information on set-up see the following sections on Computer and Mouse.

10
6 USING THE LCD PANEL
The LCD panel has a set of connectors and controls that you need to know in order to operate the device correctly.
6.1 REMOTE CONTROL
The infrared BatMouse remote control (RC) is the main user interface to the device. The RC is used to set the LCD panel correctly (to get the best possible viewing conditions) and to control the presentation.
The figure shows the different keys of the BatMouse.
Set-up should be done once with the application(s) you are running most frequently. Allow some minutes for the equipment to warm up before adjusting. Most settings will automatically be memorized individually for each source for future use.
11
The 'MEM' column in the table below indicates whether the setting is memorized for each source. For a detailed overview, see the Features section.

7 FEATURES
The LCD panel has a variety of different features implemented. This chapter explains each feature in detail.
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.
The memory can store 40 different sources/modes. Several sources are predefined, while the remaining are available for customer set-up of sources. See the Technical Data section for compatibility.
Custom sources are stored only if their sync pattern differs from any of the previous selections. The panel automatically selects a new memory location.
Most settings are stored individually for each mode, including contrast, brightness, tune etc. See the remote control table above.
7.1.3 COLOR MAPPING
A color-to-monochrome mapping scheme much like the one used in monochrome television sets is applied. This means that a color image of a human face appears natural in black and white. When using 64 shades, usually no information is lost, even in color intensive applications.
14
7.1.4 SVGA
SVGA in 800 x 600 mode is compressed both horizontally and vertically to 640 x 480 resolution. This feature is convenient when displaying irregular images (like pictures, scanned images and coarse graphics).
Regular images (patterns, text and fine line graphics) may look distorted due to the downsizing. In this case, we recommend setting up the computer in 640x480 mode for a precise image.
7.1.5 VGA TEXT
VGA text is compressed correctly from 720 x 400 to 640 x 400 mode when the image is positioned correctly. The characters maintain their shape, as every ninth pixel is dropped horizontally between each character.
7.1.6 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.
7.1.7 BRIGHTNESS
The brightness is the amount of white in an image. The brightness is adjusted to the ambient lighting conditions. Use the BRIGHT keys to adjust brightness. See also Contrast. The brightness setting is stored individually for each source.
7.1.8 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.
7.1.9 ON/OFF
This switch controls the operation of the panel. When switched on, all functions are active. When switched off, the automatic fan control is still operating, but the image is turned white. The ON/OFF switch is a toggle key.
15
7.1.10 RESET
This feature resets most controls to standard settings. See the 'MEM' column in the remote control description, where YES indicates a standard resettable setting. RESET will only reset the active mode.
A fundamental master reset may be performed by pressing all four front panel keys simultaneously for approx. 5 seconds. All settings will return to factory defaults. 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.
7.1.11 BLACK
Use the BLACK key if you temporarily want to suspend the display of images. The BLACK key is a toggle function and the screen goes black when activated. Any key pressed will release BLACK.
7.1.12 INVERSE
This option inverts the image. This setting is not memorized.
7.1.13 PALETTE
The PALETTE is by default set to display 16 greyshades regardless of application. Some applications may however look better with a different set of shades. Pressing PALETTE will cycle between 2, 16 and 64 greyshades. This setting is retained individually for each mode. RESET defaults to 16 shades.
7.1.14 FREEZE
Press the FREEZE button to lock the image displayed. This feature is useful if you want to make changes locally on your computer that should not be seen by the audience. Press FREEZE once more to resume on-line operation. Any other key pressed will also release FREEZE.
7.1.15 MAC
The MACII series of computers are equipped with slightly different 640 x 480 graphics adapters that need manual set-up to work correctly. Press this key to toggle between the basic MACII and the LC mode. The setting is retained.
16
7.1.16 FREQUENCY
This setting is usually not changed by the user. It is however provided in case of adaptation to special graphics adapters that are close to those in the compatibility list. A bad frequency setting can be seen as an image too wide or too narrow, combined with vertical, unstable bands. Press the FREQUENCY keys left or right to correct the image. The setting is stored individually for each source.
7.1.17 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.
7.1.18 MOUSE
The 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.
The LEFT and RIGHT keys emulate the left and right keys on a standard two-key mouse. For Macintosh computers, the right key is not 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 5 seconds after the last key is pressed. The DRAG key is used to activate the pull-down menus on the Macintosh.
