🔍 Key Concepts

• Compulsory radiotelegraph installations on passenger vessels under FCC rules • Difference between initial inspection and periodic/routine inspections • The phrase "at least" once every X months/years in regulatory language

💭 Think About

• Which option actually states a clear, recurring time interval for a formal inspection of the equipment itself, not paperwork or distance from a field office? • Is any choice mixing in conditions (like distance from an FCC office) that sound less like a firm requirement and more like a situational detail? • Which answer best reflects a regular safety‑oriented inspection cycle that would make sense for life‑saving communications equipment on passenger vessels?

✅ Before You Answer

• Identify which options talk about initial vs recurring requirements; focus on the one that is clearly recurring • Separate documentation/reporting responsibilities from physical inspection requirements • Look for language like "at least" once every…, which signals a minimum legal inspection frequency
