Since color temperature varies depending on the light source, the white balance should be ad-
justed whenever the main light source illuminating the object being shot changes.
Camera Adjustments
AUTO white balance adjustment (AUTO SETUP)
1.
Press the W.BAL switch to select memory “B” or “A”.

Press the AUTO WHITE button to start the auto white-
balance adjustment of the camera within a second. When
the connected camera has an AUTO SETUP function,
pressing and holding the button for more than a second
initiates the AUTO SETUP mode and starts the auto black-
balance and auto white-balance adjustment operations.
When the camera does not have the AUTO SETUP func-
tion, it is only the auto white-balance adjustment that is

When the white balance is adjusted properly, the LCD dis-
play shows “AUTO WHITE A(B) OK”.
