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)
