I'm afraid that number's ex-directory
purchase menosan Philips recalled three models of its HeartStart devices in September 2012 due to an internal electrical malfunction. The recall affects about 700,000 defibrillators sold between 2005 and 2012. The recalled HeartStart FRx and HS1 (OnSite and Home) devices include an electrical part called a resistor that could fail when high voltage is applied, and that could prevent the device from delivering the necessary shock. If the resistor fails, the device will emit an audible triple-chirp alert.
