th
, (rightmost) digit may now be adjusted.
You can select which digit you wish to adjust, by

rd
digit is now
flashing, indicating that it is now, the adjustable digit.
Cycle thru each digit of C111 and configure as charted
below, then accept by pressing
and releasing.
All four upper digits will flash once, and the new
configuration value, is displayed in 4 steady digits.
Press
and release, to configure C112, C113, … thru Df1.
