🔍 Key Concepts
• GMDSS equipment test intervals under SOLAS Chapter IV
• Typical EPIRB (Emergency Position-Indicating Radio Beacon) self‑test and log requirements
• Difference between tests done daily, weekly, and monthly for radio gear (VHF/MF/HF radiotelephone, batteries, EPIRB, etc.)
💭 Think About
• Think about which piece of equipment is most critical to confirm works very frequently (daily/weekly) versus which is normally checked less often but still regularly.
• Recall the standard schedule taught for GMDSS: what is usually tested daily, what is tested weekly, and what is tested monthly? Match each option to that pattern.
• For each option, ask: does that time interval sound too often, too seldom, or about right for this specific device, given its purpose and how it is used?
✅ Before You Answer
• Verify from your study materials what interval is specified for EPIRB self‑tests and log entries (typically in GMDSS maintenance/testing tables).
• Check which equipment (if any) must have its battery or power supply condition recorded daily in the radio log.
• Confirm whether routine radiotelephone tests are normally listed as daily, weekly, or monthly checks in standard GMDSS test schedules before deciding.
