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.
If automatic black balance adjustment cannot be made
If the black balance adjustment cannot be completed normally, an error
message will appear for about 3 seconds on the viewfinder screen (in
display mode 2 or 3).
Possible messages are listed on the next page.
Black balance adjustment error messages
Error message Meaning
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.
Refer to “maintenance manual” for information about this internal check.
Note
If the lens cable is not firmly connected to the lens connector (see
2-2), it may not be possible to adjust the lens iris. If this happens, the
black balance will be incorrect.
