The message “Executing...” appears during
execution, and changes to “OK: (color
temperature of subject)” when the
adjustment finishes.
The adjustment values are saved
automatically in the memory selected in
step 1 (A or B).
Note
If the camcorder has a zoom lens with an automatic
iris, the iris may hunt

during the adjustment. To
prevent this, adjust the iris gain knob (indicated as
IG, IS, or S) on the lens.
For details, refer to the lens operation manual.
1) Hunting: Repeated brightening and darkening of
the image, resulting from repeated response to
automatic iris control.
If the automatic white balance adjustment
cannot be made
If the white balance adjustment cannot be
completed normally, an error message will appear
for about three seconds on the viewfinder screen.
Possible messages are listed below.
If any of the above error messages is displayed,
retry the white balance adjustment. If the error
message occurs again, an internal check is
necessary.
For information about this internal check, refer to
the Maintenance Manual.

balance

This makes it possible to automatically set the
white balance to 5600K (factory default value) by
pressing the COLOR TEMP. button.
The color temperature to which the white balance
is set when the COLOR TEMP. button is pressed
can be selected from among 3200K, 4300K,
5600K, and 6300K on OPERATION
