HOW THE VISUALIZER WORKS
b
a
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
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.)
1. Press the release
button 2. Pull arm
upwards
BASIC PREPARATIONS
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).
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.
5

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.
TV-Monitor Video projector
DO NOT TOUCH THE MIRROR,
AS FINGERPRINTS CAUSE
BRIGHT AND HAZY SPOTS
ON THE PICTURE ! ALWAYS
KEEP THE MIRROR CLEAN !
CAUTION: SENSITIVE FRONT
COATED MIRROR!
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.
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.
WORKING OUTSIDE THE WORKING SURFACE
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 IMPORTANT
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:
Working plate (#5)
Light reflected directly
into camera Light reflected to the outside Light reflected to the outside
Please make sure that reflections are not caused by room light !
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
PRESET
21
The Wolfvision Visualizer VZ-15 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-15 is adjusting the preset position the green LED light (#28) is flashing.
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 Image on key (#22)).
PLEASE NOTE: Always press the Image on key before the PRESET key!

SWITCHABLE OUTPUTS
IMAGE
off on
The Composite video output (#32) and the Y/C output (#37) of the Visualizer are switchable. Use the IMAGE
keys (#21,#22) on the control panel or the remote control to switch the signal supplied from these outputs on
and off.
Independently a video signal is always supplied to the Preview video output (#31). This output can be used for
a control monitor. A constant sync signal is supplied to all switchable outputs (even in the image off mode)
eliminating monitor image distortions when switching.
READ-IN DEVICE FOR COMPUTERS
The Wolfvision Visualizer is perfectly suited for working as
a 3-D scanner for computers equipped with a Grabber Card.
A Grabber Card can be used to digitize a video signal, in order
to store and process single pictures on a computer.
Therefore just connect the Composite video output
(#32) or the Y/C output (#37) of the Visualizer to the
according input of your computers Grabber Card.
CONNECTING A NUMBER OF MONITORS

Connect a control monitor to the Preview video output (#31) of the Wolfvision Visualizer. Connect
additional monitors to the Composite video output (#32) or the Y/C output (#37) of the Visualizer by
looping them through the inputs and outputs of each monitor (as shown above).
In this way a number of monitors can be connected. However if the signal is looped through a lot of monitors
a video signal amplifier should be used in order to achieve equivalent picture quality on all monitors. The
number of monitors throught which the signal can be looped without a signal amplifier depends on the
type of monitor and on the cable lenght.

OPTIONAL LIGHTBOXES (Bottom light)
Switch off the light of the Visualizer with the Light off key (#23) and switch on the light of the lightbox.
Optional lightboxes are available from Wolfvisionin 3 different sizes.
These lightboxes improve the quality of transparencies, X-rays and slides.
While working with one of Wolfvisions optional
lightboxes, the light of the Visualizer has to be
switched off - in order to prevent reflections !!!

The Wolfvision Visualizer can also be used for image capture with a video printer. In this manner single
pictures of papers and objects can be made quickly. The lighting and focus problems are eliminated by the
Visualizers superb light and scan system. Just connect the Composite video output (#32) or the Y/C output
(#37) of the Visualizer to the according video input of the video printer.
Connect a control monitor to the video output of the video printer and (if required) a second control
monitor to the Preview video output (#31) of the Visualizer.
USING A VIDEO PRINTER
VIDEO RECORDING
video / Y/C out
video / Y/C in
VCR "stop"
video / Y/C in
video / Y/C out
A video recorder can be connected to the Wolfvision
Visualizer, so that recordings on video tape can be made.
Simply connect the Composite video output (#32) or the
Y/C output (#37) of the Visualizer to the according input
of your video recorder. When using a S-VHS or Hi-8
video recorder use the Y/C output in order to archive the
best picture quality
Connect a control monitor to the output of the video recorder
SWITCHING TO PLAYBACK OF A VIDEO RECORDER
If you want to mix your presentation with the Wolfvision Visualizer with playback of a video tape, connect the
Visualizer, the video recorder and the monitor (or video projector) as follows:
Connect the Composite video output (#32) or the Y/C output (#37) of the Visualizer to the according
input of the video recorder. Connect the video or Y/C output of the video recorder with the audiences
monitor or video projector.
Adjust the video recorder so that the picture of the Visualizer will be shown. When the video recorder
is switched to play the Visualizers picture will be interrupted by the picture of the video recorder.
Switch the video recorder to stop and the picture of the Visualizer will reappear on the monitor or
video projector.

SCANNING SLIDES
Visualizer
Slide projector
The Wolfvision Visualizer together with one or more
slide projectors allows easy scanning of individual slides
or even whole slide shows (with cross fading).
Just project the slides onto a screen (or another white
surface), switch off the Visualizers light with theLIGHT
off key (#23) and tilt the reflector head to scan the slides
(as shown on the left). In this way it is also possible to
zoom in on details in a slide
LAMP CHANGER
The Wolfvision Visualizer is fitted with a lamp changer.
If one lamp fails, there is no need to replace it immediately.
Just turn the switch of the lamp changer (#8) on the front
side of the machine to the locked position.
The spare lamp is now employed.
Thus there is no need to exchange a lamp during a presentation. The red light above the lamp changer switch
illuminates to indicate that the spare lamp (=the left lamp) is employed.
This acts as a reminder to exchange the other lamp (=the right lamp) for a new one when next convenient.
EXCHANGING LAMPS

THERMOSTAT
If the unit gets too hot (when ventilation or air extraction are covered) a built in thermostat may switch off
the light of the Visualizer. Lay open the ventilation and the air extraction and allow it to cool.
EXCHANGING A FUSE
Before changing a fuse disconnect the power cable. The fuse (#35) is situated behind a small lid between the
power socket and the main power switch. It can easily be opened with a small screwdriver etc. The left fuse
has to be exchanged. The right fuse is a spare fuse.
Please make sure that the fuse is put in the right way round (An arrow on the socket indicates the right
direction of the fuse)
CAUTION:
Only use the proper fuses with
the right specifications!
Power source: Type of fuse:
220V/240V T 1,6 A
100V/110V/120V T 4 A
Change the fuse for a new one and switch the unit on again. If the fuse fails again contact your Visualizer dealer!
INFRARED REMOTE CONTROL
For controlling the Wolfvision Visualizer with the infrared remote control aim the remote control at the
Visualizer and press the required key.
Please note that an infrared remote control can only
be used up to a certain distance to the unit. Objects
situated between the Visualizer and the infrared
remote control and a weak battery may interfere
the reception.
If the Visualizer can only be controlled from a close
distance or if it cannot be controlled at all with the
infrared remote control you may have to change the
battery.
Open the cover of the remote control (as shown on
the drawing) with a flat object (for example a
screwdriver) and replace the 9 V battery with a
new one.

Changing the frequency of the IR-control:
If a user works with two Wolfvision Visualizers and wants to control them both individually with
their infrared remote controls, he has the possibility of changing the frequency on one of the units.
For switching one Visualizer and its remote control to the second frequency just use the red switch
besides the battery of the remote control and simultaneously press the Save key on the camera control
panel (#12) and IMAGE on key (#22) on the main control panel of the Visualizer.
TRANSPORTATION IMPORTANT
IMPORTANT
For transportation press the release button for the arm (#11)and at the same time push the arm down to the
front of the unit.
DO NOT TRY TO PUSH DOWN THE ARM WITHOUT
PRESSING THE RELEASE BUTTON FOR THE ARM!
During transportation put a soft material (like paper) between the mirror and the working surface
- in order to prevent damage to the mirror !
The arm is equipped with a pneumatic damper, which makes the arm set-up easy and holds it stable when
working with the unit.
MAINTENANCE
Please note that dust on the mirror inside the unit has little effect on the picture quality (as it is out of
focal range). However the mirror on the reflector head (#10) always has to be kept clean!
Mirror: For cleaning the mirror on the arm (#10), wipe it gently with a soft (!) and lint-free tissue (no
paper !). Normal dry cleaning should be sufficient (If not, use a special optical cleaner only!)
CAUTION: Sensitive front coated mirror!
Move the tissue in vertical direction only ! (Horizontal scratches
would cause ugly reflections) Avoid high pressure !
DO NOT USE ORDINARY GLASS CLEANER OR ALCOHOL
- THE RESULT WOULD BE A SLIGHTLY BLUE MIRROR SURFACE !
The glass covering the mirror inside the unit should also be kept clean.
Cabinet: Clean the cabinet by gently wiping it with a soft cloth. Never use strong cleaning
agents such as benzine or alcohol!

Symptoms: Check points:
The right edge of the picture is black / the right
edge of an object isn't illuminated (using the
Visualizer as a video camera)
- Switch off the light with the LIGHT off key (#23) and work with room light.
(This is not a failure of the unit, see page 7 - Lighting)
No monitor picture - Are the switchable outputs (Composite, Y/C or RGBS) switched off?
Switch on with the IMAGE on key (#22)
- Is the IRIS closed? Press the IRIS open key (#20)
- Check cable connection and input of monitor/projector!
Reflections / Glare - See detailled description on page 7.
Poor picture quality on the projection screen
(using the Visualizer together with a video
projector)
- This is mostly due to bad adjustment of the video projector. Connect a
TV-monitor to the Visualizer. If the picture quality is good on the monitor
check the adjustment of the video projector.
Autoiris does not work - The autoiris function is switched off when using the IRIS keys (#19,#20).
It is switched on again when using the ZOOM keys (#15,#16)
Bad picture quality - Check the set-ups and quality of your monitor or projector.
False colors - Make sure that no neon light shines on the working surface
- NTSC: adjust color phase of monitor or projector
No color (B/W only) - Check the TV standard of the monitor or projector (PAL/Secam/NTSC)
- Check color adjustment of the monitor or projector
- Check the Y/C cable (if there is color when using the composite video
output, the Y/C cable may be defective)
No stable picture (sync) on video projector - Adjust V-Hold on monitor or HV-frequencies on projector
Vibrations in the picture - Place the Visualizer on a solid table, so that the unit is protected from
movements of people working on that table.
Infrared remote control does not work - Change the battery! (see page 11)
- If the unit cannot be controlled with the infrared remote control even from
a close distance and with a new battery it may be due to a wrong frequency
(see page 12).
The lightfield on the working surface is much
larger than the recorded area. Please note that the lightfield has to be a little bit larger than the recorded
area, otherwise it would not fit in all positions (on the working surface).
However if it is much too big check the following:
- First check if it is possible to adjust your monitor. Many TV-monitors do not
display the whole picture. Some show more of the right side, some more of
the left side etc. Check if there is an UDERSCAN function - with this
function you can display 100% of the Visualizer picture.
- If you are working with a projector (CTR) check the "blanking" of the
projector
- If you are sure that the lightfield is still much larger than the recorded area
and it is not due to a wrong adjustment of your monitor of video projector,
consult your Wolfvision dealer. The size of the lightfield can be adjusted
electronically using a special Wolfvision service software.
External Synchronization
For extrernal synchronization of the VZ-15 and adjustments of color phase, H-phase etc. please read the special
