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.

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. b The optics of the camera and the light projector are synchronized.
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.
IMPORTANT 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.
off SWITCHABLE OUTPUTS IMAGE on The Composite video output (#32), the Y/C output (#37) and the RGBS output (#40) 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.
USING A VIDEO PRINTER 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), the Y/C output (#37) or the RGBS output (#40) of the Visualizer to the according video input of the video printer.
SCANNING SLIDES Slide projector Visualizer 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 the LIGHT off key (#23) and tilt the reflector head to scan the slides (as shown on the left).
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.
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.
CONTROL PANEL OF THE VIDEO CAMERA - Settings for general users For standard use of the Wolfvision Visualizer only the white balance adjustment is really important. All other functions of the control panel (#12) of the Visualizers video camera are for specialists only.

CONTROL PANEL OF THE VIDEO CAMERA - Settings for specialists only ! menu function up data up white display bars function down data down black save For getting into the camera menu and changeing adjustments of the Visualizers video camera first press the Save key together with both ZOOM keys (#15,#16). This key combination unlocks the camera control panel. Without this key combination the camera control panel cannot be used. This is to prevent that unqualified users change the cameras adjustments.
Manual white balance adjustment: Usually you only need auto white balance adjustment - as shown on page 13. However for some special applications a manual white balance adjustment can also be made. First unlock the camera control panel with the key combination Save + ZOOM close + ZOOM wide and then press the Menu key. After that press the Function up or Function down key until the word "WHT.BAL" appears on the screen. * WHT.BAL R.GAIN B.
Other settings that can be changed: CCD IRIS Set CCD IRIS to OFF if the monitor picture is flickering. This can occur with a light, working with a different frequency. In such case, set CCD IRIS to OFF and shutter speed to FL (see next page). Also set CCD IRIS to OFF if you work with fluorescent light. As this may cause slow variations in color to the picture.
C.TEMP (Color temperature) 3200 K: for indoor shooting (Visualizer light etc.) 5600 K: for outdoor shooting (sunlight) M.PED (master pedestal) Normally set this to +00. When the black parts of the picture are too dull, you can make them look sharp by adjusting the master black level. Using a waveform monitor will make the adjustment easier. DTL (detail) You can use the DTL function to adjust the sharpness/the outlines of objects in the reproduced picture.
