🔍 Key Concepts

• GMDSS equipment testing requirements in SOLAS and FCC rules • Difference between daily, weekly, monthly, and annual checks for radio equipment • Which tests must be done by the ship’s radio operator versus by external authorities or service companies

💭 Think About

• Think about how critical VHF-DSC is for distress and safety communications. Would that suggest more frequent or less frequent testing? • Recall the typical inspection pattern: which checks are normally performed onboard by the crew and which are reserved for annual surveys or shore-based maintenance? • Compare how often other GMDSS functions (e.g., DSC test calls, battery checks) are usually required and see which time interval here best matches that level of importance.

✅ Before You Answer

• Confirm which interval is specifically linked to onboard routine testing (not shore-based maintenance). • Make sure you are not confusing formal inspections/surveys with operator functional tests. • Verify in current GMDSS guidance which equipment falls under daily checks versus weekly or monthly checks before choosing.
