HOW THE VISUALIZER WORKS
(all Visualizers)
BASIC PREPARATIONS
(all Visualizers)
1. Connect the power cable to the unit (#36) and plug it in.
2. Connect a control monitor (if required) to the Preview output (#31 or #43).
3. Connect a large viewing monitor or a projector to one of the outputs of the Visualizer.
For choosing the right output please read the previous pages!
4. Turn the main power switch (#34, on the back of the unit) to "I". The red power indicator (#29) on the control
panel indicates that power is supplied.
5. If the arm is folded down press the ARM key (#27) on the control panel, then the arm comes up automatically.
6. Press the POWER key (#28) on the control panel. The Visualizer now runs the "power-on preset" (=automatic
focusing of an A5 format on the working surface) during which the green LED light (#30) is flashing. As soon as
the green LED light stays illuminated you can start working with the Visualizer.
(The behaviour of the unit once that power is supplied to the unit or after the POWER key is pressed can be
changed in the unit's menu - see page 14 and on-screen help menu)

How it works:
A light projector (a) inside the unit projects a
lightfield (g) the same size as the pick-up area
of the built-in camera via the base mirror (e)
and the top mirror (f) onto the working
surface. The image is recorded by the camera
(b) using the same path.
The lenses of the light projector (a) and the
camera (b) are synchronized. Thus the size of
the light field on the working surface changes
when the user changes the zoom range of the
camera.
This scanning and illumination system is a
worldwide patent from WolfVision.
