All communication and safety equipment on board vessels are required to undergo annual inspections such as GMDSS radio survey and VDR/SVDR annual performance testing (APT). DSC is considered the automated watch on distress channels running on VHF, MF/HF radios. It provides a more effective distress alerting system by using satellite and digital selective calling technology. EPIRB automatically send distress signals, when coming in contact with water. Testing a 406 MHz EPIRB by allowing it to radiate outside such a container is illegal.
