Adjustments and Settings for Recording
Notes
• During black balance adjustment, the iris will be
automatically closed.
• During black balance adjustment, the gain switching
circuit will work automatically, and the viewfinder
screen will flicker several times. This is not a
malfunction.
When automatic black balance adjustment
fails
If the automatic black balance adjustment process does
not end successfully, the error message “ABB: NG”
will be displayed on the viewfinder screen for
approximately three seconds.
If this error message is displayed, try black balance
adjustment again.
If the error message continues to be displayed after
several attempts, the camera requires internal
inspection.
Refer to the Installation & Maintenance Manual for
information on internal inspection.
About black balance memory
The black balance values stored in memory will be
preserved even when the camera power is turned off.
