Auto white balance adjustment:
IMPORTANT
Each time the lighting condition changes (e.g. changing from Visualizer light to room light), the user
has to adjust the white balance of the camera, so that optimal color reproduction is obtained.
Zoom in on a white object (for example a white paper) with the same light conditions as used later for
the actual recordings.
Press the White key:
The automatic white balance adjustment starts and when 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.

Black balance adjustment:
Adjustment of the black balance is only necessary:
- when using the Visualizer for the first time
- when the Visualizer has not been used for a very long time
- when using the Visualizer after the temperature has changed dramatically
For adjusting the black balance the glass above the built in mirror of the Visualizers has to be covered
completely, so that no light gets to the camera. When the glass is covered completely press the Black
key on the control panel of the camera. Now the iris closes automatically, the light is switched off and
the Visualizer adjusts the black balance.

When finished successfully the "BLACK: OK" message appears on the monitor after a few seconds.
The new black balance is stored automatically and is preserved even if the power supply is interrupted.
If the glass is not covered completely the message "BLACK NOT O.K." or "BLACK NG" appears
on the monitor. In this case the black balance adjustment has to be repeated with a completely covered
glass.
