The VDR system, including all sensors, must be subjected to an annual performance test conducted by an approved testing or servicing facility to verify the accuracy, duration and recoverability of the recorded data. In addition, tests and inspections must be conducted to determine the serviceability of all protective enclosures and devices fitted to aid location. A copy of the Certificate of Compliance issued by the testing facility must be retained on board the ship.
