Adjusting the Black Balance
The black balance must be adjusted when: You use your unit the first time; Your unit has not been used for some time; The ambient temperature has changed substantially; The gain switchover value has been changed; or S.GAIN (super gain) has been set with the USER MAIN/ USER1/USER2 button.

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.

Set the switches as illustrated below.

AUTO W/B BAL switch: Used to perform ABB.

OUTPUT: CAM

Tilt the AUTO W/B BAL switch so that it is positioned at [ABB], then release it. The switch returns to the central position with the black balance automatically adjusted. During adjustment, the viewfinder displays the following message:
��������������ABB ACTIVE

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. By turning on the SHD.ABB SW CTL in <SW MODE> (page 178) and then continuously pressing the ABB switch for 8 seconds or longer, black shading can be automatically adjusted after the Auto-Black-Balance operation. While the black shading is being adjusted, ensure that the lens iris is closed completely until the �B-SHD OK� message is displayed in the viewfinder. However, when the remote control unit (AJ-RC10G: optional accessory) is connected, automatic black shading cannot be executed even if the ABB switch is held down. 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.

Note
During adjustment, the lens iris automatically becomes CLOSE.

Retaining black balances
Each value in memory is retained even if the camerarecorder is turned off.

The adjustment will take effect in a few seconds and the following message will appear:
��������������ABB OK

The adjusted value is automatically stored in the memory.
