ABSTRACT:
In a method of wirelessly controlling a sewing machine, a wireless receiver module receives an initial signal transmitted wirelessly and continuously from a speed control module in response to a treading action thereon, and stores a preset security code portion of the received initial signal therein. Thereafter, the wireless receiver module receives an incoming control signal transmitted wirelessly from the speed control module in response to a treading action thereon, and controls operation of a motor unit in accordance with a speed control code portion of the received incoming control signal upon detecting that an identification code portion of the received incoming control signal matches the security code portion stored therein.
