Setting up 1. Pull the arm upwards using the special pull ring (#8)
3. Connect the power adaptor to the DC-input (#15).
4. Connect your output unit (projector, monitor, video conferencing
unit etc.) to the appropriate output of the Visualier (#12 or #13).
5. Switch on the Visualizer with the power switch (#5)
2. Turn the camera head (#1) and point it at the working surface
IMPORTANT:
For choosing the right output mode please read the detailled
description on page 3!
Power-on preset:
The power-on preset is automatically activated when switching on the unit. The settings are:
Zoom size approx. 20 x 15 cm (A5), Autofocus on,Autoiris on, top light on.

The RGBHV-output (#12) can output signals in the following formats:
- XGA (1024x768 pixel) at 75Hz
- XGA (1024x768 pixel) at 60Hz
XGA (1024x768) at 60 Hz.
If you output the Visualizer image on a CRT-monitor or CRT-projector, use an output mode
with 75Hz, because 60Hz may show a slight image flickering. For LCD/DLP projectors or
monitors and video conferencing units 60Hz is the best choice. If you are unsure what is the
best mode read the user manual of the connected units.
You can change the output mode in the on-screen-menu of the Visulizer (see page 5).
.
The default setting is
Choosing the right output mode (XGA at 75Hz or 60Hz)
3
USB-PORT The USB output of the VZ-8light can be used to transfer
Visualizer images onto a computer in just 2 seconds. No
additional computer hardware (like a grabber card) is required. In
this way the Visualizer can be used as a 3-D scanner for your
computer. Just connect the USB port (#13) of the Visualizer and
the USB port of your computer, using the supplied USB cable.
A dedicated WolfVision USB-software can be downloaded from WolfVision's Internet
homepage at: www.wolfvision.com/wolf/techinfo.html. The software works under Windows
98, ME, 2000 and XP. Windows 95 and NT will not work, because they do not support USB.
EXTERNAL INPUT
A Computer can be connected to the External RGBHV input (#11) of the Visualizer.
Press the Power-key (#5) for 2 seconds to switch between the Visualizer and
Computer image to be displayed to the audience.
The signal from the computer is just looped through the Visualizer and is not processed
in any way. In order to avoid that your projector or monitor adjusts itself when switching,
it is recommended that you set the output of the computer to the same signal format
(XGA) and vertical frequency (75 or 60Hz) as the Visualizer. The default
output settings of the Visualizer is: XGA (1024x768) at 60Hz.
Connect the power cord to the light box connector (#16) on the back side of the Visualizer.
The light switch (#6) of the Visualizer can now be used to switch between the light of the
Visualizer and the light of the lightbox.
WolfVision lightboxes (optional)
Other lightboxes:
In order to prevent reflections the light of the Visualizer always has to be switched off when
working with lightboxes.

Autofocus:
When switching on the unit the autofocus is automatically switched on too. The correct focus is
continuously adjusted. The green light beside the autofocus on/off switch (#9) is illuminated if
the autofocus is on.
Please note that objects with a very low contrast (like a blank sheet of paper) are difficult to
focus. If the autofocus does not work just move the object slightly.
For special applications the autofocus can also be switched off using theAF on/off switch (#9).
The autofocus is also switched off when the manual Focus are used (see manual focusing).
.
.
Manual focusing
For manual focusing press AF-key (#9) (hold it down) and focus with the zoom keys (#10).
Shooting area on the working surface:
Eliminating reflections
In order to eliminate reflections (on high gloss photographs etc.)
just turn the light backwards slightly.
Please note that reflections can also be caused by the room light.
4
Shooting area outside of the working surface:
Turning the light backwards
In order to enable recordings with
illumination outside of the working
surface, the light of the Visualizer
can be horizontally turned an
angle of up to 250 degrees.
to infinity
Close-up adaptor lens
For shooting an object outside the working surface, in a further distance to the unit, the close up
lens (#7) has to be removed.
In this case just pull the lens away from the main optic Of the camera until it reaches the locked
position. It is impossible to remove the lens completely from the unit, therefore it can not get
lost. Before turning back the camera into the standard working position push the close up lens
back in.

5
White balance:
Correct white balance adjustment is important for true colors! The default white balance
setting when the VZ-8light is shipped is "Auto Tracking". This means that the white balance
is continuously adjusted. If the colors appear to be wrong try to
However an "Auto Tracking" white balance can never be 100% correct.
.
For a more precise white balance adjustment use the "One Push" white balance. This can
be done by completely zooming in a white paper on the working surface and pressing the
LIGHT-key (#6) for 3 seconds. When the white balance is stored an on-screen message
appears. Setting a "One Push" white balance switches off the "Auto Tracking" mode and the
current white balance setting remains in the memory even when the unit is switched off.
When the lighting conditions change (e.g. different room light or sunlight) the white balance
should be readjusted!
For specialists:
If you work with negative transparencies and an external light box, use a blank (dark) piece of the negative film for
white balance adjustment!
move any object in the
picture.
The VZ-8light can be switched between "Auto Tracking", "One Push" and "Manual" white balance
mode in the on-screen menu (see below).
Image Freeze Function
You can freeze the current image by just pressing the AF-key (#9) for 2 seconds.
Digital Zoom
Please note that the VZ-8light has an optical 12x zoom, which is digitally increased to a 24x
zoom. The smallest pickup size on the working surface without (!) digital zoom is 33 x 25mm
(1.3" x 1"). When you zoom in further the digital zoom is automatically activated and the
smallest pickup size is 17 x 13mm (0.7" x 0.5”). However please be aware that when the
digital zoom is used the resolution of the picture is not as good as before. The default setting
is that the zoom stops and a message appears on-screen when the digital zoom mode is
reached.
You can change the behaviour of the Visualizer in the digital zoom mode in the on-screen menu (see below).
For standard use of the WolfVision Visualizer it is not necessary to go into the Visualizer's
menu and change settings. Inexperienced users should not make any adjustments there.
To enter the on-screen menu press the AF-key (#9) and both ZOOM-keys (#10)
simultaneous for one second.
Settings of the Visualizer's basic functions and the built-in camera can be made here. Use
the AF-key (#9) to select and the ZOOM-keys (#10) to navigate in the menu

Changing the standard contrast (color) settings
If the picture or the colors on your screen appear to be too dark, you can lower the
overall contrast of the picture in the "Color settings" menu of the on-screen menu.
RESET OF ON-SCREEN MENU SETTINGS
All settings in the on-screen menu can be set back to the factory defaults.
“Reset Complete Menu" is one item in the on-screen menu.
Auto Power off
In the "Power-On Settings” settings of the on-screen menu you can select that the
Visualizer will be automatically switched off, if it is not used for a certain time.
The firmware (software) of your Visualizer can be
upgraded to the latest version. This can be done by
connecting a computer or a modem to the RS232 port of
your Visualizer.
