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 below (see rear
foldout).
Attach power to the LCD panel, turn the overhead projector and computer
on. 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/Mouse/Audio and Video.

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 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.
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 in the tables below 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.
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.
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.
SVGA
SVGA in 800x600 mode is compressed both horizontally and vertically to
640x480 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.

USER GUIDE LCD PANEL
15
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. Selecting
MCGA in the menu will deactivate the text compression.
BUILT IN SPEAKER
A small monitor speaker is built into the LCD panel. The speaker is good
for local monitoring, but we recommend external speakers when using the
LCD panel in a presentation. Using external speakers will disconnect the
internal speaker.
MULTISTANDARD TV SYSTEMS
The LCD panel incorporates a unique multistandard video decoder that
works with all major TV systems. NTSC, PAL and SECAM are
automatically detected. See the TECHNICAL DATA section for TV system
compatibility. (The PAL M and N systems are not covered).
PAL/SECAM ASPECT RATIO
The NTSC system maps directly in a 640 x 480 resolution display. The
PAL and SECAM systems need aspect ratio conversion to fit correctly. The
LCD panel automatically adapts to NTSC, PAL and SECAM formats and
adjusts the aspect ratio accordingly.
ON SCREEN DISPLAY (OSD)
The OSD is an information system that in plain text echoes your RC and
MENU selections on screen in real time. The OSD information is displayed
in the lower left corner of the screen. The OSD feature may be set visible
or hidden through the menu system.
See also the Menu System chapter.
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, only the left 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

USER GUIDE LCD PANEL
16
release the object. DRAG is automatically released 5 seconds after the last
key is pressed.
POINTER
The pointer is a red spot applied to the projected image, and can be moved
freely around using the cursor keys. Activating POINTER will deactivate
the MOUSE function (as the same cursor keys are used). The POINTER is
a toggle function.
The pointer may be used with any application, including live video, for
focusing attention.
The pointer may not be used when the MENU is active. The pointer must
also be switched off when controlling the mouse.
ENLARGE
The ENLARGE function doubles the image vertically. Pressing the
ENLARGE button repeatedly will display the enlarged upper part, enlarged
lower part and then go back to normal (not enlarged). ENLARGE is not
active when displaying S-VIDEO, VIDEO or SVGA. Pressing RESET will
bring ENLARGE back to normal.
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. It is also useful for freezing live
video images when showing video. Press FREEZE once more to resume
on-line operation. Any other key pressed will also release FREEZE.
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.
PROG
This key may be programmed to one of the menu functions of your choice.
In the menu, select option and then press PROG. This option is now
memorized, and available (when not in the menu) directly from the PROG
key on the remote control, until a new programming is performed.
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

USER GUIDE LCD PANEL
17
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. 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.
VOLUME
The sound volume is controlled using the VOLUME up and down keys.
MUTE
The sound is switched on and off using the MUTE key. Pressing VOLUME
up or down will also release MUTE.
COMPUTER
The computer image is displayed when pressing the COMPUTER key.
This is the power on default setting.
S-VIDEO
The S-VIDEO source is selected with this key.
VIDEO
The composite video source is selected with this key.
MIC
The MIC key toggles between the microphone input on and off. When on,
the MIC is overlaid the AUDIO input (unless sound is muted).
MENU
The menu system is invoked using the MENU key. The menu system gives
access to basic setup functions that are seldom used. See the separate
Menu System chapter for details.
MUTE
Pressing this key will toggle sound on and off. Adjusting volume will also
release mute.
ON/OFF

USER GUIDE LCD PANEL
18
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.
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.
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, 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 GUIDE LCD PANEL

8MENU SYSTEM
The menu system was developed to gain access to functions not often
used, as opposed to frequently used features that are directly available
through the RC.
Press the MENU key on the RC to invoke the menu system. When the
menu is active, the cursor keys are used to navigate between options (and
can therefore not be used for mouse control etc. at the same time). The
LEFT key is used to activate an option.
The PROG key may be assigned to most of the menu options.
Toggle functions (like OSD ON/OFF) are tagged when active and untagged
when not active.
Increase/decrease functions (like TUNE and FREQUENCY) are adjusted
using the cursor keys. OSD is used to indicate the actual setting.
The MENU key is toggling the menu on and off. The menu is also switched
off after one minute of no action. The last position in the menu is
maintained during a session, but it is reset during power off. Most
selections are memorized, unless otherwise noted.
The main menu selections SETUP, SOUND and PICTURE are explained
in detail below.
Features only available with some sources are shown in light italic
characters, while generally available functions are shown in bold
characters.
