With most Inmarsat-C systems what should the indicator lamps do when powering up?

🔍 Key Concepts

• Inmarsat-C start-up self-test behavior on most GMDSS installations • Purpose of indicator lamps during power-up versus during normal operation • Importance of following the manufacturer’s operator’s manual for specific lamp sequences

💭 Think About

• When a safety-critical communications system powers up, what might the system want to verify visually before normal operation begins? • Would it be more useful for troubleshooting if lamps briefly show a test pattern, or if they stay off until specific events (like message reception)? • How would an operator know that all lamps are working correctly at start-up?

✅ Before You Answer

• Check which option mentions a self-test or specific sequence rather than a permanent condition. • Eliminate any choice that would make fault detection of a burned-out lamp difficult during start-up. • Consider which option best matches how other GMDSS equipment (like EPIRBs or NAVTEX) often indicate start-up tests.
