NOTE
i
The default values for S1, S2 and S3 were automatically determined by SI-
DEXIS based on the exposure and entered in the text boxes of the menu.
For manual adjustment, the values displayed at this position in the text boxes
of the menu can be overwritten (see page 4-80).
First continue with the automatic adjustment. Manual determination of the ad-
justment values is required only if you fail to reach your goal via automatic ad-
justment (see page 4-79).
