When automatic white balance adjustment
fails
If the white balance adjustment process does not end
successfully, the error message “AWB: NG” will be
displayed on the viewfinder screen for approximately
three seconds.
If this error message is displayed, try black balance
adjustment again.
If the error message continues to be displayed after
several attempts, the camera requires internal
inspection.
Refer to the optional Maintenance Manual for information
on internal inspection.
When there is no time to adjust the white
balance
Set the WHITE BAL switch to PRST. The white
balance will be set automatically according to the
position of the FILTER control.
About white balance memory
The white balance values stored in memory will be
preserved even when the camera power is turned off.
There are two white balance memories, A and B.
When the AUTO W/B BAL switch is pushed to the
WHT side, the white balance will be adjusted
automatically according to the position of the FILTER
control. The adjusted value will be stored in the
selected memory. Each memory can store up to five
adjusted values, for a total of 10. The number of
values that may be stored in each memory can be
limited to 1, using the MAINTENANCE menu. In this
case, the value stored in the memory will not
correspond to the FILTER switch setting.
For settings using the MAINTENANCE menu, Refer to the
Installation & Maintenance Manual
