Performing the white balance (white bal)
In the white balancing procedure, the system adjusts the video signal in such
a way that white areas in the surgical field are also white on the video image.
• Press the <start> key to activate the white balance procedure.
 The following message is displayed:
"PLEASE PUT A PIECE OF WHITE PAPER UNDER THE MICROSCOPE"
• Place a suitable white object (e. g., a piece of white paper with a matte
surface) under the surgical microscope.
• Carry out the white balance procedure using a medium brightness level.
• Press the <start> key to start the white balance procedure.
During the white balance procedure (display: "WHITE BALANCE IN
PROGRESS") the key functions are locked.
If the white balance procedure is successfully completed, the following will be
displayed: "WHITE BALANCE SUCCESSFUL". Otherwise, the following mes-
sage is displayed on the monitor: "WHITE BALANCE FAILED". Check the set-
tings described above and repeat the white balance procedure.
The white balance is saved for the user currently selected. When the user is
changed, the white balance values pertaining to that user are loaded.
After the white balance procedure is completed, all keys are enabled again.
The determined values are saved and are available to all users each time the
device is restarted.
White balance is adjusted corresponding to the set light type. The adjustment
depends on the "LIGHT SOURCE" setting in the "INSTALLATION MENU" and
the BLUE and RED settings in the "USER MENU ADVANCED".
