66 : When ON, the start position after the treadle is depressed backward is at the beginning of the pattern or the
position of the DIPSW2-3 setting.
67 : When ON, priority returns to the sideways position after the treadle is depressed backwards, but only when
sewing pattern 5**, 6**, 7**, 8**, or 9** is selected.
However, if memory switch "66" is ON, the setting for memory switch "66" has priority.
68 : When OFF, sewing starts from the zigzag section.

stitch width for each N-backtacking operation are the same.
The method of entering the number of stitches and the zigzag width using the operation panel is the same as for
normal backtacking.
Furthermore, the switching timing can be adjusted in detail by means of the following parameters.
Switching timing from normal start backtack to reverse sewing. ----- H3
Switching timing from start backtack to normal zigzag sewing.------- b1
Switching timing from normal zigzag sewing to end backtack. ------- b3
Switching timing from reverse end backtack to normal sewing. ------ H4
