Retaining black balances
Each value in memory is retained even if the video camera-
recorder is turned off.
<Notes>
Ensure that the lens connector is connected and the lens
iris is CLOSE.
During a black balance adjustment, light is automatically
cut off.
During a black balance adjustment, the gain switchover
circuit is automatically switched.
The viewfinder screen may flicker and/or display noise;
this is not a failure.
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, move the
cursor ( ), then press the JOG dial button. The menu
option DETECTION can be found in the <BLACK
SHADING> screen, which is accessible from the
MAINTENANCE page.
Note that pressing the ABB switch for longer than five
seconds automatically performs an auto black balance
adjustment, followed by an automatic black shading
adjustment. (For more information, see the menu option
SHD. ABB SW CTL in [8-5-5 SW MODE].)
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 canceled, the value in effect
before automatic adjustment will be used.
