Preface

The manual describes the Liesegang 6.4“ TFT Data Video Projector. Please read
through this operator manual carefully before starting your projector.

Your projector is easy to use and enables com puter data to be projected in natural
colours at conferences, s eminars or an ywhere where pictur es, graphics and texts are
to be made accessible to a wider audience. This manual aim s to provide the reader
with an introduction to connecting and operating the projector to achieve maximum
success for your present ati on .

The projector can be controlled from either the built- in k eyboar d or the infr ared rem ote
control. All settings are menu-guided and the help texts are available in many
languages. The current parameters are shown on the display.

Functions used frequently, such as brightness or volume controls for video
projections, can be executed directly from the remote control without calling up the
menu system.

Due to its comprehensive r ange of autom atic func tions, the proj ector reli eves the user
of much of the work of adaptation to the computer, s creen card and m ode of display,
most tasks being reduced to a simple key press. For this ver y reason we recomm end
you familiarize yourself with all of the controls of the projector and read throu gh the
section entitled Tips for Data Projection in particular before making your first
presentation.

Faulty settings or i ncorrect connec tion of the proj ectors can lead to impairm ent of the
functions of the disp lay and the connected equipm ent. Only use the original adapter
and connection sets suitable for your computer and monitor.

Should you have any questions or doubts please contact your dealer who will gladly
pass on your request to the manufacturer if necessary.

3. Detailed Setup Information

3.1 Setting Representation, Resolution, Colours

Most computers do not just support one single screen mode but rather a series of
different modes wh ich differ in type of represe ntation (text or full graphic), resolution
(number of pixels) and number of colours.

Pre-stored standard mode settings for a variety of IBM compatible and Apple
Macintosh computers help th e projector to recog nize the current m ode and adjust for
optimum performance automatically.

Apart from this you can enter and save additional modes with any parameters by
means of the menu system . An upper limit is given by the max imum admissible pixe l
rate (Appendix 1.).

Adjust the projector to optimum display quality, as described below, by using the menu
control (see sectio n 3.5). All steps described c an be carried out via the keyboard or
the remote control:

1. Adjust the background as necessary to obtain a display with the highest possible
contrast. For use under Microsoft Windows it is recommended that you close all
applications first, a nd by using the system control, adjust the desk top background to
an even black-and-white raster.

2. Call up the main menu of the projector by pressing the MENU key.

3. Select the Setup menu.

4. Open the Setup menu by press ing the SELECT/ENTER k ey. The current mode is
displayed in the title block of the Setup menu. Change the mode field if desired.
Confirm your selection by press ing the SELECT/ENTER key

5. If desired, selec t an image format with a con ver te d c od in g of pixel and line numbers
to adapt to the current screen mode. Therefore move to the menu item Pixel and
select the image resolution. Use 800x600 for unscaled representation.

6. Select the menu item Brightness and correct the setting so t hat white areas are
projected with optimum intensity. Press the SELECT/ENTER key for automatic
adjustment.

7. Look at a finely structured area with grid lines. This area may have vertical
interference lines superimposed on it.

Select the menu item Tracking (image width) and adjust for minimum interference.
The direction of adjustment is correct when the number of lines decreases. The setting
is optimal when no more interference lines can be seen. An automatic setting of
tracking and synchron ization can b e called up by oper ating the SELECT/ENTER key.
This may not work, if a uniform pattern is displayed on the projector.

8. Synchronize the phase position of the pixel frequency and scanning frequency.
Choose the menu item Sync. Contour flick er can be observed with som e settings as
shown in the following figure:

9. In a range of sever al settings an im age is pr ojected that is free of contour flick er. If
the sync-setting is correct, the image will improve as shown in following figure:

10. An automatic setting of the synchronization can be called up by using the
SELECT/ENTER key.

11. Minor interference, where one colour meets another, can be corrected by manually
adjusting the Brightness and Contrast. Normally, the contrast should be set to
approximately the medium value. Lower values cause an increase in background
intensity.

12. To leave the Setup menu, press the MENU key.

13. If parameter settings have been changed, a warning is displayed. Confirm the
changed settings by using the SELECT/ENTER key.

14. Center the projected image, if necess ary, with the cursor keys or the disk pad of
the remote control.

4. Tips for Data Projection

With the projector it is now possible to pres ent graphics , computer im ages, CAD data
and other image contents, which use colour to make up the image, to a large audience

22 User Manual for TFT 6.4“ Data Video Projector

without problems and with little effort. It is easy to forget that the impression of the
image which an individua l gets near to the video m onitor is different to that which an
observer gets some meters away from the projection screen.

To conclude with here are some tips on how to give a successful computer data
presentation:

#

Adjust the projector for your computer and save the settings for all screen modes.

#

Try out your presentat ion beforehand in peace and quiet. Look at the projection from
where the audience are seated.

#

Pay attention to good legibility by selecting suitable font sizes and colours.

#

Try the effect of the Inverse representation. Ch ange the setting of brightness both
manually and with t he OPTIMIZE button. Familiarize yourself with the co ntrols in order
to achieve the best possible effect for your presentation.

#

Pay attention to optimal room lighting: sunlight or light from lamps should not fall
directly on the projec tion screen. The room should be lit so that it is comfortable but
not too bright.

#

Use a projection screen with a high degree of reflection.

CE

This equipment complies with the re qu ir ements of the EU guide lines 8 9/33 6/ EWG for

electromagnetic compatibility and therefore bears the CE sign. The equipment
satisfies the following standards:

EN 55022 Interference voltage and perturbing radiation
EN 50082-1 Immunity to interference
EN 61000-4-2 Electrostatic discharge
EN 61000-4-3 HF irradiation
EN 61000-4-4 Burst test

Warning!

This is a class A apparatus . T his appar atus can caus e r adio int erf erence in r eside ntial
quarters; in such circumstanc es the user m ay be asked to tak e appropriate s teps and
be responsible for these.

Note

The European standards EN 55022 and EN 50082 diff erentiate bet ween equipm ent of
class B (for use in living areas) and equipment of class A. Residential quarters are
defined as those areas where a rad io or tele vision rec eiver is opera ted withi n a radius
of 10 m. Equipment of class A m ay produce a h igher level of interference voltage but
must itself also be less sensitive to interference caused by other devices than
equipment of class B. This eq uipment fulfills the requir ements of class A. If radio or
television receivers are us ed in the immediate vicinity of this eq uipment then usually
interference is not to be expected as long as these receivers are connected to a
properly installed aeria l s ystem.
