Reason for recall

Insulin pumps manufactured with speakers from Revision A and B may malfunction ("Malfunction 16") which prevents audible alerts and causes the pumps to become inoperable and stop infusing insulin which could result in a hyperglycemic event, which may lead to injury and/or hospitalization.

FDA-determined cause: Nonconforming Material/Component
