Chapter 3 Adjustments and Settings 1 Set the OUTPUT/DCC switch to CAM. 2 Push the AUTO W/B BAL switch to BLACK and release the switch. The message "Executing..." appears during execution, and changes to "Done" when the adjustment finishes. Adjustment values are saved to memory automatically. Notes • During the black balance adjustment, the iris is automatically closed. • During the black balance adjustment, the gain selection circuit is automatically activated so you may see flickering on the viewfinder screen, but this is not a fault. • Output from the i.LINK connector stops temporarily if you execute black balance adjustment during i.LINK output. Output from the connector resumes when black balance adjustment finishes. If automatic black balance adjustment cannot be made If the black balance adjustment cannot be completed normally, an error message will appear for about three seconds on the viewfinder screen. Possible messages are listed below. Error message NG: Iris Not Closed NG: Timeout NG: Out of Range Meaning The lens iris did not close; adjustment was impossible. Adjustment could not be completed within the standard number of attempts. The difference between the reference value and the current value is so great that it exceeds the range. Adjustment was impossible. If any of the above error messages is displayed, retry the black balance adjustment. If the error message occurs again, an internal check is necessary. For information about this internal check, refer to the Maintenance Manual. Note If the lens cable is not firmly connected to the LENS connector, it may not be possible to adjust the lens iris.
