Ease of programing

The user can combine 99 freely programmable pocket programs with
up to 25 seam patterns.
For the sewing of sequences, 10 pocket sequences are available.
Each pocket sequence can be put together in any desired order out of
a maximum of 6 pocket programs.
With the "angled pocket version" Class 745-28 all practically suitable
angles can be pr o gra mm ed by the operator with the push of a bu tt on .

5.3.2 Sewing distance measurement

For measuring the seam length, two possibilities are available.Use the
pocket programme for selecting. The two possibilities are reciprocally
