Abstract
In a sewing machine having a remote battery powered foot pedal control, that communicates with the sewing machine proper via a wireless signal, a monitoring system that periodically monitors the status of the battery and provides that information from the foot pedal control, along with speed instructions, to the sewing machine proper. A display on the sewing machine informs the operator when battery change time is approaching and when replacement is urgently needed. If the battery is not replaced when replacement is urgent, the sewing machine ceases operations.
