(2)Software verification, validation, and hazard analysis must be performed.
(3)Performance data must demonstrate the electromagnetic compatibility, electrical safety, battery safety, and wireless compatibility of the device.
(4)The device components that contact the patient must be demonstrated to be biocompatible.
(5)Performance data must validate the reprocessing instructions for the reusable components of the device.
(6)Labeling must include:
