§  80.318   Use of alarm signals.

   (a) The radiotelegraph or radiotelephone alarm signal, as appropriate,
   must only be used to announce:

   (1) That a distress call or message is about to follow;

   (2) The transmission of an urgent cyclone warning. In this case the
   alarm signal may only be used by coast stations authorized by the
   Commission to do so; or

   (3) The loss of a person or persons overboard. In this case the alarm
   signal may only be used when the assistance of other ships is required
   and cannot be satisfactorily obtained by the use of the urgency signal
   only, but the alarm signal must not be repeated by other stations. The
   message must be preceded by the urgency signal.

   (b) In cases described in paragraphs (a)(2) and (3) of this section,
   the transmission of the warning or message by radiotelegraphy must not
   begin until two minutes after the end of the radiotelegraph alarm
   signal.
