Bernina 580 Manual page 96

For an even sewing start (the first stitch) the foot control must be
pressed and the fabric moved simultaneously. This also applies for
sewing points and straight stitching within a round form.
If the BSR function is deactivated and later re-activated without the
sewing computer being switched off in between, the last selected
BSR mode is active.
When exceeding a certain speed, adhering to regular stitch length
cannot be guaranteed.
Make sure that the lens on the bottom of the BSR foot is clean (no
fingerprints, etc.). Clean lens periodically with soft, slightly damp
cloth.
