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 started by this button.

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

NOTE

●The light in the button lights up during an auto white- balance adjustment or an auto setup of the camera and turns off when it completes.

●The light in the button also lights up when the FAW (Full Auto White) balance adjust function of the cam- era is working.

●The LCD display shows the operating status of the auto white balance adjustment or auto setup operation.

If the white balance is not adjusted properly, the LCD display shows an error message.
