and so remove the bar. When you are finished shooting
the monitor press the Clean Scan button for two
seconds to switch off the Clean Scan function.
When the Clean Scan function is on, the non-standard

White Balance switch
This momentary switch is used to start the automatic
white balance process. The camera, when pointed at
a white area in the centre of the picture, measures and
stores a colour temperature setting in the FL, AW1 or
AW2 memory position.
The white balance switch only operates if the colour
temperature is set to the FL, AW1 or AW2 position.
Refer to Section 5 for more information on how to use
the automatic white balance.
Note
Black balance is not necessary with this camera
because of the continuous automatic black control
circuits.
