The default value for S1 was automatically determined by SIDEXIS based on
the exposure and entered in the text box of the menu.
For manual adjustment, the value displayed at this position in the text box of
the menu can be overwritten (see page 4-89).
First continue with the automatic adjustment. Manual determination of the ad-
justment value is required only if you fail to reach your goal via automatic ad-
justment (see page 4-88).
