state.
Notes
•When using a camera control unit or remote control
unit, if the W/B BALANCE switch of the control unit
is set to MANUAL, it is not possible to carry out
black balance adjustment on the camera.
•The black balance cannot be adjusted while
recording. Since the readout mode of the CCD
changes during black balance adjustment, some
disturbance may be generated in the video output
signal from the camera. If automatic black balance is
activated when any peripheral equipment is
connected, noise may be generated or warning
indication may light, but this is not a problem.
If black balance adjustment cannot be
completed automatically
The warning message “ABB:NG” appears in the
viewfinder.
Make the necessary corrections, then carry out the
process again.

readjustment is not normally necessary after powering
the camera off or simply when lighting conditions
change.
