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 400 W halogen or metal-
halide. Best results are obtained in a dimmed room with no direct sunlight
shining in.
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

6USING THE LCD PANEL
The LCD panel has a set of connectors that you need to know in order to
operate the device correctly.
6.1 REMOTE CONTROL
The infrared 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 remote control.
* Grey area does not apply for this product.
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.

6.2 CONNECTORS
All connectors are positioned on the right hand side of the LCD panel. See
the technical data section for pinouts of the various connectors.
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 FUNCTION
POWER Low voltage power supply
COMPUTER Connector for analog RGB in/out
6.3 LOCKING THE PANEL
To avoid having your LCD panel stolen you can use a safety lock. On the
connector bracket described above you will find a slot marked with the
symbol for instalment of your safety lock.
Please consult the user instructions included with your lock
before connecting it to the panel.

7FEATURES
The LCD panel has a variety of different features implemented. This
chapter explains each feature in detail.
DUAL SAFECOOL SYSTEM
The cooling operation is controlled by the overhead projector light (OHP).
This safety feature ensures that the fans are always operating as long as
the OHP is turned on. When the OHP is turned off, the fans automatically
stop 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 each time 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. Some sources are
predefined, while the remaining are available for customer set-up of
sources. See the Technical Datasection 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.
VGA TEXT
VGA text is compressed correctly from 720x400 to 640x400 mode when
the image is positioned correctly. The characters maintain their shape, as
every ninth pixel is dropped horizontally between each character.

USER GUIDE LCD PANEL
13
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.
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.
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, an incorrect frequency setting can be
observed as an image too wide or too narrow, combined with vertical,
unstable bands.
TUNE
This feature is used to stabilize the image. An untuned image can be seen
as sideways instability or ‘swimming’.
BLACK
Use the BLACK key on the RC, if you temporarily want to suspend the
display of images. The BLACK key is a toggle function, and the screen
goes black when activated. Blanking the image is done using the ON/OFF
key. Any key pressed will release BLACK.
MAC LC
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 640 x 480 resolution. Pressing the MAC
key toggles between the MACII LC 640 x 480 mode and the standard
mode. An erroneous setting will typically be seen as an image too wide or
too narrow, as well as vertical unstable bands.
REAR
The REAR mode is used for rear projection , i.e. projection from the back
of a screen, mirroring the image.

USER GUIDE LCD PANEL
14
POSITION
Due to minor variations in graphic cards, the horizontal and vertical
position may need adjustment. Select POSITION, then press LEFT and
use the cursor keys.
VGA text mode (720 x 400) is correctly displayed when the image is
positioned appropriately.
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). RESET will only reset the mode active.
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.
ON/OFF may also be used to blank the screen.

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. The glass may be
hard to get out, as the springs holding the glass are designed to avoid the
glass falling out . Place the unit upside-down on a soft cloth to avoid
scratches. Using both hands, 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.
