ADDITIONAL FEATURES OF VZ-7D / VZ-5D
Digital Zoom (VZ-7D, VZ-5D)
All portable Visualizers have an optical 12 x zoom lens. In addition the VZ-7D and the
VZ-5D have a 2x digital zoom extension, which increases the overall zoom range to
24 x zoom. The smallest pickup size on the working surface without (!) digital zoom is 23 x
31mm (0.9"x1.2"). When you zoom in further the digital zoom is automatically activated and
the smallest pickup size is 12x16mm (0.5"x0.6").
However please be aware that when the digital zoom is used the resolution of the picture is
not as good as before.
Manual white balance (VZ-7D only)
Automatic white balance adjustment is described on page 5. For some applications you
may require a manual white balance setting. This can be done by pressing the LIGHT-key
(6) for 3 seconds. When the unit is switched off and on again it is set back to automatic
white balance.
(Other white balance settings for specialists see page 24 - for experienced users only)
Slide Drawer (VZ-7D only)
(This is a new function of the VZ-7D which can only be found on units produced after June 2000.)

Serial control input, RS 232 (VZ-7D only)
The serial port can be used to control the Visualizer through an
external device, like a remote control system for a whole
conferencing room.
It can also be used to control the Visualizer through a computer.
A special Windows-software for PC is available from WolfVision.

surface (very important!). Then insert a slide in the slide drawer.
The camera automatically recognizes the slide and focuses on
the slide.
In case the slide is out of focus:
- Make sure that the slide is firmly in place
- Make sure that the ZOOM is not in the maximum tele
position (=smallest picture). Use the ZOOM-keys (10).
