During a black balance adjustment, the gain switchover
circuit is automatically switched.

If you find the black shading annoying after performing
an auto black balance adjustment, adjust the black
shading. To do so, go to the menu option DETECTION

button. The menu item DETECTION (DIG) is found in the
<BLACK SHADING> screen on the MAINTENANCE
page.
When you set the SHD.ABB SW CTL menu option to
“ON” and press the AUTO W/B BAL switch for 8
seconds or longer, [B-SHD READY] is displayed in the
viewfinder and black shading can be automatically
adjusted after the automatic black balance operation.
While the black shading is being adjusted, the “B-SHD
ACTIVE” message is displayed in the viewfinder.
Ensure that the lens iris is closed completely until the
“B-SHD OK” message is displayed in the viewfinder.
The menu item SHD. ABB SW CTL is found in the <SW
MODE> screen on the CAM OPERATION page.
However, when the remote control unit (AJ-RC10G:
optional accessory) or extension control unit (AG-
EC4G: optional accessory) is connected, automatic
black shading cannot be executed even if the ABB
switch is held down.
z
To cancel the automatic black balance adjustment in
process (the viewfinder displays “ABB ACTIVE”), flip
the AUTO W/B BAL switch down to [ABB] again.
If automatic adjustment is cancelled, the value in effect
before automatic adjustment will be used.
Each value in memory is retained even if the camera-
recorder is turned off.
