Setup scroll bar, and select a setup from the list.

To edit the white balance values that you saved, open the image setup (i.e.,

Exposure Time(s) (User Defined Exposure)
There are two options for entering user-defined exposure times. With the SPOT camera,
you can:

Manually enter the value(s).
§
Allow the camera to calculate the value(s).
§
Recall the exposure times and the gain used for the previous image capture.
Each of these options is discussed below.
