measures a white area in the middle of the picture and stores a colour temperature setting in

The WHITE BALANCE button only operates if the colour temperature function is in a preset
position (AW1 or AW2) and the colour bars are switched off.

camera viewfinder.

If the measurement is successful, the light in the button and the measurement window are
switched off. If the measurement is unsuccessful, the light in the WHITE BALANCE button is
orange.
If the button is pressed during the measurement process or at the end of an unsuccessful
measurement, the value stored in AW1 or AW2 is reset.
