Rescue Ready defibrillator technology self-tests all main components (battery, hardware, software, and pads) daily. Powerheart Automatic and Semi-Automatic Defibrillators complete a partial charge of the high-voltage electronics weekly, and a full charge monthly Calculates electrical impedance and if subsequent shocks are necessary, our proprietary STAR biphasic technology escalates the energy to deliver therapy at an appropriate, higher level.
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Symptoms: Delivered energy outside tolerance on the analyser, will not charge, or charges slowly.
Root cause: HV capacitor / charging-circuit ageing, or an output-relay fault.
Symptoms: Short standby, readiness indicator shows service, unit fails the self-test on battery.
Root cause: Aged battery pack or a charging fault.
Symptoms: "Check pads", "connect electrodes", no ECG through pads, poor paceing capture.
Root cause: Worn therapy cable, expired pads, or a paddle / connector fault.
Symptoms: A monitoring parameter drops or is implausible.
Root cause: Patient cable / sensor or the parameter module.
Symptoms: No printout, event data will not transfer.
Root cause: Thermal recorder or the data / Wi-Fi interface.

Sub-supplier s documentation for specific Printed Circuit Boards (PCB) is insufficient to determine if the devices conform to specifications.
Defibrillation electrodes may increase electrical impedance over time. If impedance becomes too high, the AED will fail the electrode self-test and it will not be Rescue Ready, the AED STATUS INDICATOR will be RED and the AED will beep. This is normal behavior when the impedance limit is exceeded. The high impedance electrodes require replacement.
The affected Automated External Defibrillators (AEDs) contains a circuit board manufactured with a component that may fail unexpectedly due to a supplier manufacturing defect. If the component were to fail during a rescue attempt, the AED may not deliver defibrillation therapy.
Cardiac Science Corporation (CSC) has identified two errors, 0x48 and 0x99, that have repeatedly occurred during a device self-test in the G3 installed base over the last 6 years. These self test errors cause the device to enter into a service required state. CSC remind owners/operators of the Powerheart AED devices to verify the "Rescue Readiness" of their equipment and follow maintenance pro
Cardiac Science Corporation (CSC) intent to end service support and discontinue accessory sales of Powerheart G2 Automated External Defibrillators. Customers are recommended to choose a replacement AED prior to the current AED displaying any "Service Required" self test messages.
A component of the AED device may fail during a rescue attempt and the AED will not be able to deliver therapy.
The K302 relay switch of the G3 series AED product line may experience an early failure. If the K302 contacts are open at the time of rescue, there is a possible delay in therapy or failure to deliver therapy.
Potential for devices not to deliver therapy
Certain models of Powerheart G3 AEDs may not have received adequate electrical safety testing prior to being shipped from the factory. Affected models are: Powerheart 9300A, 9300C, 9300D, 9300E, 9300P, 9390A, 9390E, CardioVive 92532, 92533, NK 9200G, 9231, and Responder 2019198 and 2023440. The affected devices were manufactured between October 29, 2003 and February 10, 2009.
Potential for AED to not deliver defibrillation therapy.
Instructions For Use is not clear about how the AED voice and text prompts will differ when the adapter is used.
Some Powerheart AED Model 9300A may contain a suspect electronic component and there is a remote likelihood that the function of this device may be interrupted during the charge.
AEDs may contain an electronic component that does not meet its full operating specifications. The AEDs with this suspect electronic component may not functionn properly and may interfere with the AED's ability to delivery therapy. In the event that charge noise is presrent it will delay the first defibrillation shock in the 3 shock sequence.
Some of the high voltage capacitors in the recalled external defibrillators have had extended charge times resulting in self-test failures following which the defibrillator cannot be used/cannot be turn on.
Some of the recalled defibrillator batteries contain an incorrect fuse which could open resulting in a defibrillator which will not work.
