Bobbin Sensor Setting for BERNINA Machines

When using DecoBob™ prewound bobbins, we recommend turning off your machine's lower thread sensor, if applicable. Because DecoBob™ is an exceptionally fine 80wt thread, the sensor may not always detect it accurately, resulting in unnecessary low bobbin thread alerts.
This setting does not affect your machine's stitching performance.
