PRECAUTIONS

Make sure that sufficient air circulation for cooling the unit is possible (ventilation slots on the
left and right side of the unit)

If the Visualizer is not used for a long time turn off the main power switch (#34)!
If there is any abnormality (abnormal noise, smell, smoke etc.) turn the power off immediately

and contact your Visualizer dealer!
USE THIS MACHINE ONLY WITH THE CORRECT VOLTAGE AS

SHOWN ON THE TYPLABEL !
Do not use a damaged power cord. This may cause short circuits or electrical shocks!
Do not modify the Visualizer or operate it without the cover panel firmly in place, to prevent danger!
DO NOT EXPOSE THE UNIT TO EXTREME HEAT OR MOISTURE !
Do not expose the Visualizer to water, metallic objects or any flammable material.
Do not place liquids or wet objects on the working surface! Put them in front of or behind the

unit and use it as a camera. If you work with wet hands, cover the remote control with plastic wrap!
DO NOT CARRY THE VISUALIZER HOLDING IT ONLY BY ITS

MIRROR ARM (#1) !
DURING TRANSPORTATION PROTECT THE UNIT FROM EXCESSIVE

SHOCKS !
Avoid installing the Visualizer in environments where there are radiations.
Avoid installing the Visualizer in locations exposed to strong magnetic fields or electrical

currents. This could cause monitor image distortion or even damage to the CCD camera.

HOW THE VISUALIZER WORKS

A light projector (b) inside the Wolfvision Visualizer projects
the light via a mirror inside the unit and a mirror on the reflector
head onto the working surface. The video camera (a) inside the
unit scans the picture where the light falls.

The optics of the camera and the light projector are synchronized.
This means that when the size of recording area is increased or
decreased with the ZOOM-keys (#15,#16), the size of the
illuminated area on the working surface is also increased or

b

a

decreased.
Thus the illuminated area on the working surface always indicates

where the camera scans the picture. (In fact, the scanned area is
fractionally smaller than the light field.)

BASIC PREPARATIONS

1. Press the release
button

2. Pull arm
upwards

1. Press the release for the arm (#11) and simultaneously pull the arm upward. Make sure that the arm is
extended to its full length.

2. Connect the power cable to the unit (#36) and plug it in.

3. Connect a control monitor (if required) to the Preview video output (#31).

4. Connect a large viewing monitor or a video projector to the Composite video output (#32), the Y/C output
(#37) or the RGBS output (#40). These outputs can be switched on and off with the IMAGE keys (#21,#22)
of the control panel.

For live image projection we highly reccomend using the Y/C output (#37). The picture quality (especially
the resolution) is much better than with the Composite video output (#32). The picture of the Y/C output even
looks a bit sharper than the picture of the RGBS output, as the signal passes a sharpness enhancer. For signal
processing we reccomend using the RGBS output (#40), as this is the original (unprocessed) signal.
The RGBS output also offers the best color reproduction.

5. 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.

6. Press the POWER on key (#28) on the control panel. The Visualizer now runs the "factory setup"
(=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.

WORKING ON THE WORKING SURFACE

1. Place your subject material on the working surface. For background use either the white side or the black
side of the working plate. For some objects the best presentation can be made with colored background.

2. Tilt the reflector head (#10) so that the object is illuminated.

DO NOT TOUCH THE MIRROR,
AS FINGERPRINTS CAUSE
BRIGHT AND HAZY SPOTS
ON THE PICTURE ! ALWAYS
KEEP THE MIRROR CLEAN !

TV-Monitor

3. Select the enlargement required with the ZOOM keys (#15,#16) on the control panel or the
infrared remote control.

4. Adjust the sharpness with the FOCUS keys (#17,#18) on the control panel or the infrared remote control.

Video projector

CAUTION: SENSITIVE FRONT
COATED MIRROR!

WORKING OUTSIDE THE WORKING SURFACE

For showing 3-dimensional objects with the Wolfvision-Visualizer, just place them on the working surface
and adjust ZOOM and FOCUS (as mentioned). Due to a special Wolfvision lens the object can be up to 9.7"
(25 cm) in height. If the object is to big for the working surface or if you want to show it from the side just
place it behind or in front of the unit and tilt the reflector head.

In this way it is also possible to make recordings
of subjects in the room or surrounding area, as
with a video camera by just tilting the reflector
head.

Due to the great focal range it is possible to
show details even from a great distance to
the unit.

If you want to record people you should turn off the light with the LIGHT off key (#23), so that they are not
dazzled.

AUTOIRIS / MANUAL IRIS

The Wolfvision Visualizer is equipped with autoiris. That means that the brightness of the camera image adjusts
automatically. Using the IRIS keys (#19,#20) on the control panel or the remote control the autoiris function is
switched off. In this mode the Iris can be adjusted manually.

When using the ZOOM keys (#15,#16) on the control panel or the remote control the autoiris function is
switched on again

6

REFLECTIONS / GLARE

Reflections can appear only in the bottom half of the working surface, where the light is reflected directly into the
camera. In this case, move the object upwards and tilt the reflector head slightly.

If this is not possbile (e.g. with very big objects), pull the working plate to the front of the unit (as shown below)
and tilt the reflector head accordingly. As the working plate is magnetic, it will stick to the unit.

Reflection: No reflection: No reflection:

LIGHTING

The lighting system is fixed for working on the working surface. Because of the oblique mounting of the
camera and the light projector of the Visualizer the light-field shifts to the left when the distance between the
Visualizer and the scanned object is increased. This means that the light field no longer exactly shows the
recorded area. The edges of the light field may also be unsharp. In this case switch off the Visualizers light
with the LIGHT off key (#23) and work with room light.

PRESET FUNCTION

2

The Wolfvision Visualizer VZ-35 offers the possibility of programming two presets for the functions Zoom,
Focus, Iris, Light and Image. They can be recalled with the PRESET 1 (#25) and PRESET 2 (#26) key.
This function is very useful for example if a user requires one preset for papers on the working surface and
one preset for an object placed in front of the unit. During his presentation the user just has to press the
PRESET 1 or PRESET 2 key when he changes from one object to the other.

While the VZ-35 is adjusting the preset position the green LED light (#28) is flashing.

PRESET

1

For programming a preset just adjust Zoom, Focus, Iris, Light and Image as required and simultaneously
press the PRESET 1 or the PRESET 2 key together with the Save key (camera controls, #12)).

PLEASE NOTE: Always press the Save key before the PRESET key!
