PRECAUTIONS WARNING! RISK OF ELECTRIC SHOCK DANGEROUS VOLTAGE INSIDE 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.

ATTENTION: Check which Visualizer model you have! This is a combined user manual for the 3 professional WolfVision Visualizer models: VZ-17, VZ-37 and VZ-47. It is noted in each headline if the following chapter applies to all 3 Visualizer models or just to one or two of these models.

HOW THE VISUALIZER WORKS (all Visualizers) 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.
WORKING ON THE WORKING SURFACE (all Visualizers) 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.
BOTTOM LIGHT / LASER CENTER MARKER (all Visualizers) The LIGHT key (#21) can be used to switch between: . "Top light" (with Synchronized Lightfield) "Bottom light" (with Laser Center Marker) and "Light off" Laser center marker . The bottom light should be used for dark transparent materials such as x-rays or for very small transparent materials such as slides. .
PRESET FUNCTION (all Visualizers) 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.
TEXT ENHANCEMENT (all Visualizers) IMPORTANT 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.
INFRARED REMOTE CONTROL (all Visualizers) 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. 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.
Left: spare fuse Right: active fuse EXCHANGING A FUSE (all Visualizers) 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). The type of fuse is: T 3,15A.
WHITE BALANCE ADJUSTMENT (all Visualizers) IMPORTANT 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.
EXTERNAL SYNCHRONIZATION (VZ-37 and VZ-17 only!) 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. 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.

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 13) 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 ligh
Symptoms: Infrared remote control does not work The lightfield on the working surface is much larger than the recorded area. Check points: - 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 12). 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).
