Backing up Stitches Not documented in Embroidery Unit 7570 Manual! Follow directions on page 21. Do not press the foot petal UNTIL you have backed up sufficient stitches. Each time key 9 is pressed you will be backing up 6 stitches. i.e. to go back 18 stitches, press key 9 three times. (no need to press the button each time) NOW, lightly tap the foot pedal. The machine has backed up. If you have gone too far back press key 0 for one stitch forward. If you did not back up enough press key 9 again several times and THEN lightly tap the foot pedal.
