Digital Selective Calling (DSC) radios are an essential part of marine communication systems, allowing for automated distress signaling and selective calling. Service includes testing the DSC functionality, ensuring the system is properly connected to the vessel’s other communication systems, and verifying that distress signals are transmitted correctly. Proper maintenance helps ensure the radio meets SOLAS and GMDSS requirements and remains fully operational. Regular servicing of the VHF DSC radio improves the safety of the vessel by enabling rapid emergency communication and reducing the risk of communication failure.
