AUTO W/B BAL switch
Automatic white balance adjustment begins.
During adjustment, the message "AWB: EXECUTING" will be
displayed on the viewfinder screen.
After about one second, the message "AWB: OK" will be
displayed, and the adjustment process will complete. The
adjusted value will be automatically stored in the selected
memory (A or B).
Note
When using a zoom lens with automatic iris control capability,
1)
hunting may occur. Adjust the lens iris gain control (labeled
IG, IS, S, etc.).
1) Hunting: The automatic iris responds over and over, and the image
repeatedly darkens and lightens.
For more information, refer to the operation manual for the
lens.
About white balance memory
There are two white balance memories: A and B. When you
execute automatic white balance adjustment, the adjusted
white balance value and the settings of the filter select knobs
will be stored in either memory A or B, selected with the
WHITE BAL switch.
The white balance values stored in memory will be preserved
even when power is turned off.
When power is turned on again, the white balance in memory
corresponding to the current WHITE BAL switch setting is
retrieved.
By setting FILTER WHT MEM to ON on the <OTHERS 2>
page of the MAINTENANCE menu, you can store a white
balance value for each of the built-in CC filters in memory A
and B individually. In this case, a total of 8 white balance
values can be stored as the camera has four CC filters. The
settings of the filter select knobs are not stored when you
adjust white balance with FILTER WHT MEM set to ON. In this
case, the white balance in memory corresponding to the
current WHITE BAL switch and CC filter select knob settings
is retrieved when power is turned on again.
If automatic black balance or white balance
adjustment fails
If the adjustment process does not end successfully, the error
message "ABB: NG" or "AWB: NG" will be displayed on the
viewfinder screen for approximately three seconds.
If this error message is displayed, try the adjustment again.
If the error message continues to be displayed after several
attempts, the camera requires internal inspection.
