Minimum interval for testing a compulsory VHF-DSC radiotelephone installation at sea?

Explanation:
Regular checks of safety-critical radio gear are essential, and for a VHF-DSC setup the daily test is the minimum interval while at sea. This is because DSC is used to alert and coordinate distress and other important calls, so you need to confirm the transmitter, receiver, and DSC circuitry are functioning each day, that the vessel’s identifiers (like MMSI) are correctly programmed, and that the emergency signaling features respond properly. If you wait longer than daily, a fault could go unnoticed and leave you unable to initiate a DSC call when needed. Less frequent intervals (weekly, monthly, annual) don’t provide the same assurance of readiness for day-to-day safety at sea.
