14 Memory of pattern data
Main body, Media
• Main body : Max. 999 patterns (Max. 50,000 stitches/pattern)
• Media : Max. 999 patterns (Max. 50,000 stitches/pattern)
15 Temporary stop facility
Used to stop machine operation during a stitching cycle.
16 Enlarging / Reducing
facility
Allows a pattern to be enlarged or reduced on the X axis and Y axis independently when
sewing a pattern. Scale : 1% to 400% times (0.1% steps)
17 Enlarging / Reducing
method
Pattern enlargement / reduction can be done by increasing / decreasing either stitch length
or the number of stitches. (Increasing/decreasing stitch length only can be performed when
pattern button is selected.)
