CHOOSING THE RIGHT VIDEO OUTPUT IMPORTANT
Y/C output (S-VHS - #37 and #38)
RGBS output (#41)
VZ-37:
VZ-17:
On the VZ-17 the RGBS-signal is actually only a converted Y/C-signal. (As the VZ-17 has a 1-chip camera and no 1-
chip camera has a true RGBS output). This output is intended for units which do not have Y/C-input. The quality is
better than composite video but not better than Y/C !
Most RGB-monitors or projectors use a separate Sync connection. For units without a separate Sync connection
the Sync Signal can be added to the Green-signal.
The "Sync on green" function can be switched on and off by simultaneously pressing the following three keys:
IMAGE (#17), FOCUS near (#19), FOCUS far (#19). The factory setting is "Sync on green - off".
If "Sync on green" is switched on, make sure that no separate sync cable is connected - the result
could be a picture with too much green!
Component output (#41 - VZ-37 only)
The RGBS output of the VZ-37 can be switched to Component output (YUV) by simultaneously pressing the following
three keys: IMAGE (#17), IRIS dark (#24), IRIS bright (#24).
The connections are the following: Red=R-Y, Green=Y, Blue=B-Y
Composite video output (#32)
Only use this output if the display device does not have Y/C or RGBS input. This is the oldest standard with the lowest
bandwidth the quality is not as good as with the other outputs.
Preview video output (#31)
This is a composite video output for a control monitor. It's the only output that is not switched off, when the IMAGE key
(#17) is used. Do not use this output for the audience's monitor or projector!
For live image projection it is recommended to use the Y/C output as the signal passes a sharpness enhancer. It even
looks better than with the RGBS output of the VZ-37. Only the Component output (YUV) of the VZ-37 offers a better
quality than the Y/C-output.
The VZ-37 offers a true RGBS-signal. Red, Green and Blue are directly connected to each of the 3 chips of the
camera. As a result this output offers the best color reproduction. This signal is also recommended for image
processing as it is the original (unprocessed) signal.
(On the VZ-37 this output can be switched to YUV - see below)

HOW THE VISUALIZER WORKS
All outputs of the WolfVision Visualizers - except the Preview output (#31 or #43) - are switchable. Use the
IMAGE key (#17) to switch the signal supplied from these outputs on and off. Independently an image is always output
by the Preview output (#31 or #43). 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.
When the output signal is switched off the IMAGE key on the control panel is illuminated red.
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.
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 13 and on-screen help menu)

WORKING ON THE WORKING SURFACE
When the Visualizer is turned on the focus automatically adjusts to the working surface level.
As a resultit is not necessary to readjust the focus if you are only working with flat material (text, photos etc.).
Furthermore, due to the great depth of focus of the Visualizer it is rarely necessary to readjust the focus. Only very
high objects require a focus adjustment.
If you have misadjusted the focus and want to set it back for working with flat objects just press both focus keys (#19)
on the control panel of the unit (not on the remote control!) simultanously. This activates theAuto focus for flat
objects. (With this function the Visualizer checks the mirror position and optimizes the focus for the working surface
level.)
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 25 cm (9.7") 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 top mirror by hand or using the MIRROR keys (#12).
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 in every distance
to the unit.
If you want to record people you should turn off the light with the LIGHT
key (#21), so that they are not blinded by the light.
If the top light of the Visualizer is used (normal working condition) a synchronized lightfield always marks the
pick-up area of the built-in camera on the working surface. The alignment of this lightfield is made for working on the
working surface.
Because of the oblique mounting of the camera and the light projector of the Visualizer the lightfield shifts to the left
when the distance between the Visualizer and the scanned object is increased (when capturing images outside of the
working surface). This means that the lightfield no longer exactly shows the recorded area. In this case switch off the
Visualizers top light with the LIGHT key (#21) and work with room light.

1. Place your subject material on the working surface. A synchronized lightfield on
the working surface marks the pick-up area of the built-in camera! Just place your
subject material in the illuminated area.
2. Select the enlargement required with the ZOOM keys (#13).
3. Use the MIRROR keys (#12) on the control panel or the remote control to change
the vertical position of the pick-up area. The upper mirror can also be moved by
hand! This does not cause any harm to the motor of this mirror!
4. Adjust the sharpness with the FOCUS keys (#19)
DO NOT TOUCH THE MIRROR SURFACE, AS FINGERPRINTS CAUSE
BRIGHT AND HAZY SPOTS ON THE PICTURE ! ALWAYS KEEP THE
MIRROR CLEAN ! CAUTION: SENSITIVE FRONT COATED MIRROR!

The working surface of the Visualizer (#9) has a special crystalline white color, which is
especially designed for perfect reproduction of transparencies.
Even though the professional Visualizers have a built-in bottom light it is recommended to
use the top light for transparencies, because of the better color reproduction and the
advantage that the Synchronized Lightfield still shows the pickup-area of the built-in
camera.
However in these situations it is recommended to use the bottom light:
- If the transparency is very dark
- If the transparency is very wavy and causes reflections
- If the room light causes reflections on a transparency
.
WORKING WITH TRANSPARENCIES
BOTTOM LIGHT / LASER CENTER MARKER
8
Please note that the macro mode has the following limitations:
- The depth of focus is not as large as in the fully extended position of the arm.
- The largest pick-up size is only about 42 x 33 mm (1.6" x 1.3").
- When zooming the Synchronized Lightfield stays at a larger size and no longer marks the pick-up area of the
built-in camera. As a substitute the Laser Center Marker (see above chapter) is activated.
If sufficient depth of focus in the macro mode is more important than big enlargements, it is possible to switch the
Visualizer from 12x zoom to 11x zoom in the Visualizer's menu (see page14). The smallest pick-up size in the 11x
macro mode is only 33 x 25mm (1.3" x 1"), but the depth of focus is larger than in the 12x macro mode.

marker
Please note that for technical (optical) reasons the laser center marker can not show the exact middle center of the
pickup area in every position of the arm. This is not a failure of the unit! However it is always very close to the center.
This Laser Center Marker is only visible on the working surface and NOT on the picture the audience sees. For
safety reasons the Laser Center Marker is automatically switched off when the top mirror is tilted to record outside of
the working surface. If required the Laser Center Marker can also be switched off completely in the unit's menu (see
page 13 and on-screen help menu).
The LIGHT key (#21) can be used to switch between:
"Top light" (with Synchronized Lightfield)
"Bottom light" (with Laser Center Marker) and
"Light off"
The bottom light should be used for dark transparent materials such as x-rays or for
very small transparent materials such as slides.
Using the bottom light has the disadvantage that the Synchronized Lightfield of the top
light no longer marks the pick-up area of the built-in camera. However as a substitute
the Visualizers have a built-in Laser Center Marker, which marks the center of the pick-
up area. This can also be used for quick positioning of objects (especially with big
enlargements, like when picking up a slide)
.
.
.
In the fully extended position of the arm, the smallest
pick-up area is 42 x 33mm (1.6" x 1.3"). When pressing the
MACRO key (#18) the length of the arm is automatically reduced,
this allows for greater enlargements. In the macro mode the
smallest pick-up area is: 30 x 22mm (1.2" x 0.9").
There is no loss of resolution in the macro mode, as this is an
optical and not a digital zoom extension.
When the macro mode is activated the MACRO key on the control
panel is illuminated red.
.
.

PRESET FUNCTION
WolfVision Visualizers offer the possibility of programming three presets for the functions: Zoom,
Focus, Iris, Light, Image, Text, Macro and Mirror position*. They can be recalled by pressing one of the three PRESET
keys (#14) on the control panel or the remote control.
This function is very useful for example if a user requires one preset for papers on the working surface, one for
working with slides (bottom light) and one for an object placed in front of the unit. During his presentation the user just
has to press one of the PRESET keys when he changes from one object to the other.
For programming a preset just adjust every function as required and then keep one of the PRESET keys pressed for
more than 4 seconds. The on-screen menu tells you when the preset is stored.
When switching on the unit the "Power-on Preset" is activated (=Top light on, Zoom at 210 x 148mm, Focus
on the working surface level, Mirror center). This function can be switched off in the units menu (#23) if required - see
help menu (#25).
This "Power-on Preset" can also be recalled during operation of the unit by pressing the RESET key (#20)
WolfVision Visualizers are equipped with autoiris. That means that the brightness of the camera
image adjusts automatically. Using the IRIS keys (#24) the autoiris function is switched off. In this mode the Iris can be
adjusted manually.
When using the ZOOM keys (#13) the autoiris function is switched on again. Before the iris closes completely, the
Visualizer automatically dims the light.
The standard auto iris level can be set brighter or darker in the unit's menu (#23) - see help menu (#25).
For video recording simply connect the Composite video output (#32)
or the Y/C output (#37) of the Visualizer to the according input of your
video recorder.
Please note that the Y/C output offers the better picture quality than
the Composite video output. Connect a control monitor to the output of
the video recorder. The RGBS output (#40) of the VZ-37 can be
switched to YUV for professional videorecorders with component input
by simultaneously pressing the following keys: IMAGE (#17), IRIS dark
(#19) and IRIS bright (#19).
A Visualizer can be used as document- and object-camera for video
conferencing systems. Furthermore it can be used as a 3-D scanner for
computers in order to digitize Visualizer images for image processing etc. The
computer has to be equipped with a frame grabber card or another video INPUT
device.
In order to archive the best picture quality please read the chapter "Choosing
the right video output" (page 5).

Please note that LCD- or DLP-projectors require some special adjustments for perfect
projection of a Visualizer image:
DETAIL / SHARPNESS Enhancers
Nearly all LCD- or DLP-projectors have a built-in sharpness enhancer for video signals. The level of this sharpness
enhancement is adjustable with a setting called DETAIL (on most projectors). Please note that for the readability
of small characters a LOW detail setting for Visualizer images is better!
CONTRAST / BRIGHTNESS
With the standard setting of many LCD- or DLP-projectors the picture is too bright if black text on a white background
is being projected. There are 3 possible ways of correcting this problem:
Option 1: Close the Visualizer's iris slightly with the IRIS dark key (#19). This is the quickest solution but it is
only temporarily, because once you press a zoom key the unit switches back to autoiris and the
picture will be as bright as before.
Option 2: Reduce the standard auto iris level in the units menu (#23) - see help menu (#25) for details. This will
keep the iris level permanently lower than usual. However this has the disadvantage that the output picture
may be too dark for other units connected to the Visualizer (e.g. monitor, video recorder, computer)
Option 3: Reduce the brightness of your LCD- or DLP-projector. Better projectors can store individual brightness
settings for each input. So an ideal setting for the Visualizer input can be made, while keeping the setting
for the other inputs (e.g. computer, video recorder).
To make the ideal LCD-/DLP-projector adjustment for Visualizer projection, we recommend to put a white sheet of
paper with text and some objects with different colors on the working surface. Keep an eye on the readability of the
text and the accuracy of the colors.
In order to check how the actual output signal of a Visualizer looks, we recommend to connect a CTR monitor (not
an LCD monitor!) to the Visualizer and use the monitor picture as reference image.
WINDOW Function (only for certain projectors)
SPECIAL ADJUSTMENT OF LCD/DLP-PROJECTORS
For improving the readability of text, sketches and x-rays press the TEXT-key (#16). This mode enhances the
contrast of the picture. Please note that in this mode the colors are darker than usual. To switch off the text
enhancement mode press the TEXT key again. While the text mode is activated the TEXT key on the control panel is
illuminated red.
TEXT ENHANCEMENT
Image up-calculated to
panel resolution Image with "window" function
The Visualizers output a picture of approx 752x582 pixels
(depending on model). Most modern LCD-/DLP-projectors have
a NATIVE RESOLUTION of 1024x768 pixels. In order to display
the Visualizer image on the full screen size the projectors up-
calculate the image to their panels pixel size.
Most projectors do this conversion perfectly, however with some
projectors some picture quality is lost in this process. That is
why some projectors have a "Window"-function. With this
function only as many pixels of the display as required for the
video picture are used and the image is not "blown up" to the
full panel size.

EXCHANGING LAMPS
INFRARED REMOTE CONTROL
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 batteries.
Open the cover on the back of the remote control by hand and replace
the two 1.5 V AA batteries with new ones.
If a user works with a number of WolfVision Visualizers simultaneously
each unit can be set to a different infrared code, so up to 4 units can be
controlled individually with their remote controls.
11
THERMOSTAT
If the unit gets too hot (improper ventilation or air extraction) a built in thermostat will switch off the light of the
Visualizer. Verify that proper ventilation and air extraction is available and allow the unit to cool.
1. Turn the unit off (#28) and disconnect the
power cord!
2. Remove the bottom light (#9) by pulling the
two black bolts (situated left and right of the
control panel) to the front and lift up the
bottom light plate.
3. Remove the lamp exchange cover (#11)
by turning it to the right and lifting.
4. Change the lamp (or both lamps)
Before changing the lamp allow it to cool or use
a cloth to avoid burning a finger! When pressing a
new lamp into the socket use a cloth to prevent
fingerprints on the lamp!
Only use 12 V/100 W halogen lamps (socket: GY 6,35), types: Philips 7023, Osram HLX 64625, Ansi FCR,
LIF A1/215 etc. These are relatively inexpensive standard OHP lamps.
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 with the reception.
front back (open)
AUTOMATIC LAMP CHANGER
WolfVision Visualizers are fitted with an automatic lamp changer. If one lamp fails, there is no need to replace it
immediately, as the automatic lamp changer automatically switches to the second lamp. When the unit changes lamps
there is an on-screen message saying: "Changing lamp".
When switching on the unit the Visualizer checks if both lamps are working. If one lamp fails there will be anon screen
message for a couple of seconds displaying "Change lamp". This prevents a user from forgetting to change a
defective lamp.
If a lamp is not fully defective but worn out and as a result the light output is quite weak, you can switch manually to
the second lamp by pressing the LIGHT key (#21) for 1 second.
In order to change the infrared codes, first open the 4 screws on the back of the remote control and set the DIP-
switches to the required code A, B, C or D (see graphic above). Then press the MENU key (#23) on the control panel
of the Visualizer for one second until the on-screen menu appears. Then go into the "Misc. Settings" menu and set the
"IR Code" to A, B, C or D.

IMPORTANT
WHITE BALANCE ADJUSTMENT
The type of fuse is: T 3,15A. Do not use any other type !
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.
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).
Each time the lighting condition changes, the user should adjust the white balance of the Visualizer's camera,
in order to optimize the color reproduction. The Visualizer's top- and bottom light have the same color temperature
so normally a new white balance adjustment is not necessary when changing from one light to the other, but if there is
also room light or sun light shining on the working surface, the white balance should be adjusted.
Top light: First, zoom in on a white object (for example a white paper) until there is only white on the screen. Then
press the W.B. key (#22).
Bottom light: Turn on the bottom light with the LIGHT key (#21). Remove everything from the working surface. Zoom to
the smallest picture. Then press the W.B. key (#22).
You can adjust the white balance either for the top or for the bottom light and it works well with both lights.
When the white balance adjustment is finished successfully the message "WHITE OK" appears on the monitor after a
few seconds. The new white balance is stored automatically and is preserved even if the power supply is interrupted.

IMPORTANT
CLEANING
CAUTION: Sensitive front coated mirror!
Move the tissue in vertical direction only ! (Horizontal scratches would
cause ugly reflections) Avoid high pressure !
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!
Change the fuse for a new one and switch the unit on again. If the fuse fails again contact your Visualizer dealer!
With most Visualizers the fuse never fails during the whole lifetime of the unit.
EXCHANGING A FUSE
DO NOT USE ORDINARY GLASS CLEANER OR ALCOHOL
- THE RESULT WOULD BE A SLIGHTLY BLUE MIRROR SURFACE !
Left: spare fuse
Right: active fuse
Mirror: Please note that dust on the base mirror (#2) inside the unit has little effect on the picture quality (as it is out of
the focal range). However the top mirror (#3) always has to be kept clean! Wipe the mirror gently with the
WolfVision Visualizer cleaning cloth.
Please note: Switch off the power before cleaning a mirror in order to make sure that the Laser Center Marker is off.
(The Laser Center Marker is automatically switched off anyway, when the mirror is turned to the outside)

TRANSPORTATION
ON-SCREEN MENU / CAMERA MENU
When the menu appears on the screen, settings of the Visualizer's basic functions can be
made using the 4 select keys (#26). On the Visualizers VZ-37 is also possible to change a
great number of settings of the built-in camera.
If you require more information on a function in the on-screen menu just set the cursor in
the respective line and press the HELP key (#25). A detailed description of this function
appears on the screen.
The functions of the on-screen menu are not described in this user manual as the help menu is an integrated part of
the Visualizer's software and checking this information on your Visualizer assures that you get the right information for
your unit.
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 try to make any adjustments there. That is why the keys for the camera menu
(#25 and #26) are dark on the control panel and not easy accessible.
These keys and the on-screen menu only become visible after pressing the MENU key (#23) for 1 second !
This is to prevent that the menu key is pushed by accident by an inexperienced user.
The settings in the on-screen menu can be set back to the factory defaults. "Reset" is one item in the on-screen menu.
In case you can not read the menu on a screen you can also set the unit back to the factory defaults by simultaneously
pressing the keys: RESET (#20) + MENU (#23).
Please make sure that you pack up the Visualizer in the supplied box as explained in this graphic.
This is very important to avoid damage to mirror, arm and other sensitive parts of the unit!

IMPORTANT
The following chapters are for experienced users only:
RESET OF ON-SCREEN MENU SETTINGS / PRESETS

EXTERNAL SYNCHRONIZATION
If Visualizer images are mixed and processed (fade-in, fade-out, mix/wipe) with images from one or more video
cameras (or Visualizers) using a special effect unit without TBC (time base corrector), all units connected must be
genlocked.
14
SOFTWARE UPGRADE
The software of your Visualizer (including the on-screen help menu) can easily be upgraded to the latest version. It can
be done by connecting a computer or a modem to the RS232 port of your Visualizer.
Please consult your WolfVision dealer or check our website (http://www.wolfvision.com/wolf/techinfo.html).
Please note that this reset-function does not reset the sync settings of the RGBS outputs or the RGBS / YUV
setting of the VZ-37! (To reset those settings use the key combinations listed on the back of this manual)
The on-screen menu also offers the possibility to store three different menu settings as Menu-presets.
Serial port Serial protocol
Pins: 2:RX, 3:TX, 5:GND
9-pin D-Sub connector
on unit, male, front side
CONTROL CONNECTORS
A detailed description of the serial protocol (including status
report and position setting) is available on request from your
WolfVision dealer or can be downloaded from our website:
http://www.wolfvision.com/wolf/techinfo.html.
Genlocking is achieved by supplying the same composite video signal (VBS) or black burst (BB) signal to the
Extern Sync input (=Genlock input) of each unit connected.
In order to genlock the WolfVision Visualizer with another video signal, simply connect this signal to the Sync input
(#33) of the Visualizer where a composite video or a black burst signal can be connected.
With a VZ-37 fine adjustment of color-phase (SC) and H-phase can be made in the unit's on-screen menu.
With a VZ-17 it is necessary to open the unit and adjust the settings with a screwdriver on the camera itself. Please
leave this to a technically experienced person, as there is sensitive and potentially dangerous electronics inside the
unit!
Start with H-phase adjustment, followed by rough adjustment of "0/180" followed by fine adjustment with SC.
Genlock operation with a playback signal of a video recorder is only possible if the signal is time base corrected via
a TBC device.
POSITIVE/NEGATIVE SWITCHING (VZ-37)
The output image of the Visualizers can be switched from positive to negative in the on-screen menu.
TIP: If you require negative images often, you can store a Preset with these settings (see page 9). This saves you
from entering the on-screen menu for switching.

TROUBLESHOOTING
Symptoms: Check points:
No power - Is a power cord connected?
- Is the main power switch (# 34, on the back of the unit) switched to "I"?
- Check fuse! (#35)! (see page 12)
Bright and hazy spots in the picture - Is the top mirror (#3) or the glass over the base mirror (#2) dirty?
If yes clean it BUT BE CAREFUL - (see page 13)
Low light - Is the lamp worn out?
- Are you using the Visualizer with the correct voltage?
- Is the lamp correctly placed in the socket?
No light - Is the light switched off (LIGHT keys #21)?
- Is the lamp burned out?
- Is the light slot covered?
The left 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 (#21) and work with room light.
(This is not a failure of the unit, see page 7 - "Synchronized Lightfield")
No monitor picture - If the IMAGE key (#17) is illuminated red on the control panel, then the
switchable outputs are switched off? - Switch on with the IMAGE key
- Is the IRIS closed? Press the IRIS bright key (#24)
- Check cable connection and input of monitor/projector!
- When using an RGBS output check if the correct Sync-Mode is selected
(see page 5)
Reflections / Glare - The working surface of the Visualizer is reflection free (provided that the
material is not very wavy). If there are reflections in the picture it must be
due to room light. Switch off the room light!
Poor picture quality on the projection screen
(using the Visualizer together with a projector) - This is mostly due to bad adjustment of the projector. Connect a monitor to
the Visualizer. If the picture quality is good on the monitor check the
adjustment of the projector.
Autoiris does not work - The autoiris function is switched off when using the IRIS keys (#24).
It is switched on again when using the ZOOM keys (#13)
Bad picture quality - Check the set-ups and quality of your monitor or projector.
- On VZ-37 check the camera set-ups in the on-screen menu. If
you are unsure about the settings use the "reset" function in the menu or
use the key combination: RESET (#20) + MENU (#23).
False colors - NTSC: adjust color phase of monitor or projector
- Adjust the white balance (see page 12)
Too muchgreen in the picture
(when using the RGBS output) - Use either SYNC ON GREEN or SEPARATE SYNC but not both at the
same time! (see page 5).
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 problems)- RGBS-output: Check Sync connection. Use either SYNC ON GREEN or
SEPARATE SYNC (see page 5).
- Adjust V-Hold on monitor or H/V-frequencies on projector or monitor
Picture is too bright (when using an LCD video
projector) - An LCD projector should be adjusted for Visualizer projection see page 10 for details.
VZ-37: Wrong colors or bad picture quality
(using the RGBS / YUV output of VZ-37) - Check if the Visualizer and the monitor or video projector are both switched to either RGBS or YUV. The VZ-37 can be switched to the other standard
by simultaneously pressing: IMAGE, IRIS open and IRIS close.
Infrared remote control does not work - Change the battery!
- 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 11).

Symptoms: Check points:
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 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 UNDERSCAN 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 or your projector,
consult your WolfVision dealer. The size of the lightfield can be adjusted
electronically using a special WolfVision service software.
The Laser Center Marker is slightly right or
slightly left of the middle of the pick-up area. - This is not a failure of the unit. It is optically impossible that the Laser Center
Marker is 100% in the horizontal middle of the picture with every length of
the arm (macro mode on or off). But it is adjusted to be very close to the
middle with every length of the arm.
The size of the lightfield does not change when
zooming in and out You are in the MACRO mode - press the MACRO key (#18) -see page 8
You are in the MACRO mode - press the MACRO key (#18) -see page 8
You are in the MACRO mode - press the MACRO key (#18) -see page 8
You can change the macro mode from 12x macro to 11x macro in the unit's
menu. The enlargements are not as big as before but the depth of focus is
higher in the 11x macro mode -see page 14 and on-screen help menu.
It is not possible to record the whole working
surface. The zoom stops at a largest picture of
approx. 42 x 33mm (1.6" x 1.3").
Depth of focus is not as large as usual
Depth of focus in the macro mode in too low for
my application.
Projection picture is frozen Check if the projector has frozen the picture (search for a FREEZE key on
the projector or its remote control)
