Chapter 4 Adjustments and settings for recording
4-1-2 Adjusting the black balance
<Notes> � Check that the lens connector has been connected and that the lens aperture is set to CLOSE. � While the black balance is being adjusted, the aperture is automatically set to the light-shielding status. � While the black balance is being adjusted, the gain selector circuit is switched automatically. Flicker or noise may appear on the viewfinder screen, but this is not indicative of malfunctioning. � If the black shading is still unsatisfactory although the �ABB OK� message is displayed, perform menu operations to open the <BLACK SHADING> screen from the MAINTENANCE page, move the arrow mark (>) to the DETECTION item, press the JOG dial button, and proceed with the black shading adjustment. If the ABB switch is held down for 5 or more seconds, the black shading can be automatically adjusted after the ABB operation. (See the SHD.ABB SW CTL item under �7-5-5 SW MODE.�) � If the AUTO W/B BAL switch is pushed down to the ABB position again while the black balance is being automatically adjusted (ABB ACTIVE), the adjustment will be aborted. The adjusted value in this case is the value before automatic adjustment was performed.

The black balance needs to be adjusted in the following cases: � When the unit is used for the first time � When the unit is used after it has not been used for a prolonged period of time � When the unit is used in an ambient temperature which has fluctuated significantly � When the value selected for the gain switch has been changed � When the super gain setting has been performed using the USER MAIN, USER1 or USER2 button � When the gamma ON/OFF setting has been changed
