White Balance Adjustment
Carry out white balance adjustment when the illumination condition (color temperature) is changed.
Adjust the white balance when using the camera for the first time or after replacing the lens.
1. In the MENU mode, set up WHITE BAL: MEM 3200K or MEM 5600K.
2. Turn off the MENU screen to select the DIRECT mode.
3. Provide a proper aperture value of lens using the auto iris function or manually.
4. Put an white object in the subject image, and zoom it up.
5. Hold the AWB button pressed for about 2 seconds for automatic white balance adjustment.  With MESSAGE
RTN:ON, AUTO WHITE appears.  At the end of successful adjustment AUTO WHITE:OK appears.
Note:
If adjusted under a light source that has a flicker component, such as fluorescent or mercury, the white balance accuracy
can be impaired.  Change the electronic shutter mode (Sub-menu 1 Shutter or Variable) setting to reduce flicker before
engaging the auto white balance adjustment.
6. If white balance adjustment cannot be made, any of the following messages will appear.  Take a proper procedure
according to the error message, and then try white balance adjustment again.
