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.

retry the black balance adjustment.
If the error message occurs again, an internal
check is necessary.
For information about this internal check, contact
your vendor or a Sony service representative.
