1INTRODUCTION
The LCD panel is a state of the art projection device that can be connected
to several sources, like the popular IBM, Apple and NEC computers, in
addition to NTSC, PAL or SECAM video (through an external adapter).
The ability to display a multitude of true colors simultaneously, in real time,
makes it the ideal choice for presenting computer generated text and
graphics, television and video.
Applications include presentations, software training, educational use,
advertising, information boards and other situations where a small or large
audience shares information.

5SETTING 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 halogen or metal-
halide. Best results are obtained in a dimmed room with no direct sunlight
shining in.
Connect the cables and power supply as described in the rear foldout page
(see Connection Layout)). Cable adapters are not used with VGA, only
with MACII and NEC9801.
Connect cable (1) between the LCD panel and the computer. Use the
Y-split on the computer end to connect the monitor.
If you have a Macintosh, EGA, CGA or NEC computer, insert applicable
adapters (2) and (3) as described in the table below.
Connect the power supply to the LCD panel (4).

6USING 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 device correctly (to get the best
possible viewing conditions).
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.

The 'MEM' column indicates whether the setting is memorized for each
source. For a detailed overview, see the Features section.

7FEATURES
The LCD panel has a variety of different features implemented. This
chapter explains each feature in detail.
AUTOMATIC FAN CONTROL
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.
SET-UP MEMORY
The user controlled set-up that usually is done when the panel is adapted
to a new computer, is automatically memorized for future use. The set-up
information is stored in a non-volatile memory.
The memory can store 40 different sources/modes. Approximately 10
sources are predefined, while the remaining 30 are available for customer
set-up of sources.
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. See the remote control table above.
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 source.
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.

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. Use the TINT controls on the RC to adjust.
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. A special transmissive screen is
needed. A typical application is in exhibitions. REAR is a toggle function on
the RC.
PALETTE
Usually, the palette is set to display the maximum number of colors
available, regardless of application. Some uses may be better off with a
reduced set of colors available. By pressing the PALETTE switch on the
RC, the color palette is cycled between 512, 4096 and 2.1 million colors.
The palette setting is retained individually for each source.
ON/OFF
This switch controls the operation of the panel. When switched on, all
functions are active. When switched off, only the automatic fan control is
operating. The ON/OFF switch is a toggle key.

USER GUIDE LCD PANEL
13
MAC
The MACII series of computers are equipped with slightly different graphic
interfaces that need manual setup on the RC to work correctly. Default is
the MACII standard interface of 640x480 resolution. 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. When the VGA text format of 720x400 was defined, it was
made to look like the MCGA mode graphic sync pattern of VGA. (This
means that on most panels, text is displayed as an underscanned,
unstable image).
ADJUST
When viewing a text image, first tune the image (see TUNE) for a stable
view. If you are not able to tune a stable text image, you are probably in
MCGA mode. If necessary press TEXT to toggle, then retune. Then press
the ADJUST keys until correctly shaped characters appear. Once this
procedure is performed, it will be retained for future use. This setting will
not affect any graphic mode settings.
FREQUENCY
This setting is usually not changed by the user. It is however provided in
case of adaptation to special graphic cards that are close to one of those
in the compatibility list. Generally, a bad frequency setting can be
observed as an image too wide or too narrow, combined with vertical,
unstable stripes. Press the FREQ keys (up or down) to correct the image.
The setting will be retained individually for each source.
TUNE
This feature enables a stable image. An untuned image can be seen as
sideways unstability or 'swimming'. Press the TUNE buttons until a stable
image is achieved. The setting is retained individually for each source.

USER GUIDE LCD PANEL
14
POSITION
Due to minor variations in graphic cards, the horizontal and vertical
position may need adjustment. Use the four arrow keys of POSITION for a
correct set-up. The position is then memorized automatically for each
source.
RESET
This feature enables standard settings of most controls (see the 'MEM'
column in the remote control description, where YES also indicates a
standard setting).

9MAINTENANCE
From time to time, the housing and protection glasses may be cleaned
with a damped, non abrasive cloth, possibly using a mild detergent to
remove spots.
The upper protection glass is not removable, as it only needs cleaning
from the outside (the inside is sealed to the LCD module).
The lower protection glass can be removed for cleaning. Place the unit
upside-down on a soft cloth to avoid scratches. Using two fingers, press
the protection glass out of the guide rail and slide out. Be careful not to
touch or to drop any objects inside the housing. Replace the glass after
cleaning.
