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

.
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!

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
