Fittings/Connectors.
Examine all cable connectors for general condition. Electrical contact pins or surfaces should be straight and clean. Verify that leads and electrodes are firmly gripped in their appropriate connectors. Disconnect the connectors and look for misaligned pins, damaged receptacles, and carbon deposits from arcing. Pay particular attention to the connector where disposable defibrillation electrodes are connected as there have been reports of damage and failure to defibrillate associated with failure at this connection.
