The VHF Digital Selective Calling (DSC) system is a vital component of ship communication, especially in emergencies. Regular service ensures the DSC radio system is operational, allowing the vessel to send distress signals to other ships and shore stations. Maintenance tasks include checking the system’s communication range, ensuring the DSC function is enabled, verifying connectivity, and testing the distress button. Proper servicing ensures safety by maintaining an effective means of communication during emergency situations, improving the vessel’s responsiveness.
