LIFEPAK 500 AEDs in high-use environments (Emergency Medical Services) may detect a patient connection due to mechanical wear-through of the contact plating on the therapy connector. Wear-through of the connector exposes base metal on which an oxide layer may form result in the device not recognizing a patient is connected. When the circumstance arises, the device will provide the user the "CONNECT ELECTRODES" message. In agreement with the FDA and the PMA standards, this device is out of service.
