The IVS offers a choice for White Balance between

• an automatic control (AWB)

• fixed setting of indoor (IND)

• fixed setting for outdoor (OTD)

• and a full manual control of white balance (MAN).

White balance can be adjusted in two different ways. It is

possible to control it using the keyboard on the IVS or

using the on-screen control menu.
