●When the foot controller is plugged in, (start/stop button) cannot be used to start or stop sewing.

●When sewing is stopped, the needle remains lowered (in the fabric). The machine can be set so that the needle will stay up when sewing is stopped. For details on setting the machine so that the needles stay up when sewing is stopped, refer to “Changing the needle stop position” (page 10).

■Sewing reinforcement stitches

When sewing stitches other than straight or zigzag stitches that are secured with reverse stitching,

of each other.
