MEMO
Error messages
If the adjustment ends abnormally, an error message, as described below, blinks for about 5 seconds.
•NG: OBJECT (Improper object)
Displayed when there is not enough white color on an object or the color temperature is not suitable.
Replace the color temperature conversion filter or use another white object and
•Do not adjust using any highly reflective objects, such as metal, etc., as this may result in improper white balance adjustment.
•The FAW (Full Auto White balance) function cannot pro- vide optimum white balance with a subject outside the FAW adjustment range, for example when it contains only a single color or not enough white color.
•The accuracy of the FAW (Full Auto White balance) is inferior to that of the Auto white balance.
•When the power is turned on with the FAW mode selected, it takes about 10 seconds for the FAW adjust- ment to be completed.
Do not shoot within this interval.
Full Auto White Balance (FAW)
The FAW function adjusts the white balance value automati- cally as the lighting condition changes.
This mode is convenient when you have no time to adjust the white balance or when the camera is moved frequently in and out of places under different lighting conditions.
Setting procedure
The FAW function can be activated with the FAW item on the SWITCH MODE menu screen. The FAW function can be allocated to one of the white balance switching switches A, B, or PRESET.
