Title 47 › CHAPTER 5 — WIRE OR RADIO COMMUNICATION › SUBCHAPTER III — SPECIAL PROVISIONS RELATING TO RADIO › Part II — Radio Equipment and Radio Operators On Board Ship › § 353
Ships that have a radiotelegraph station must carry radio officers for safety. Passenger ships and cargo ships without a radiotelegraph auto alarm must have at least two radio officers. A cargo ship with a working radiotelegraph auto alarm must have at least one radio officer who has at least six months of prior service as a radio officer on U.S. ships. While a ship is sailing in the open sea outside a harbor or port, it must keep a radio watch whenever the station is not handling authorized traffic. A cargo ship with a working auto alarm may instead keep at least eight hours of radio watch per day in total. The Commission can set exact watch hours when needed for safety. On ships with an auto alarm, the alarm must be running at all times while at sea whenever no radio officer is on watch.
