Sec.  80.1133   Transmission of safety communications.

   (a) In a terrestrial system the announcement of the safety message must be
   made on one or more of the distress and safety calling frequencies specified
   in  Sec. 80.1077 using digital selective calling techniques. A separate
   announcement need not be made if the message is to be transmitted through
   the maritime mobile-satellite service.

   (b) The safety signal and message must normally be transmitted on one or
   more of the distress and safety traffic frequencies specified in  Sec. 80.1077,
   or via the maritime mobile satellite service or on other frequencies used
   for this purpose.

   (c) The safety signal consists of the word SECURITE. In radiotelephony, it
   is pronounced as in French.

   (d) The safety call format or the safety signal indicates that the calling
   station has an important navigational or meteorological warning to transmit.

   (e) In radiotelephony, the safety message must be preceded by the safety
   signal, repeated three times, and the identification of the transmitting
   station.

   (f) In narrow-band direct-printing, the safety message must be preceded by
   the safety signal and the identification of the transmitting station.

   (g) Error correction techniques, in accordance with ITU-R Recommendation
   M.625–3, “Direct-printing Telegraph Equipment Employing Automatic
   Identification in the Maritime Mobile Service,” with Annex, 1995, as
   specified in  Sec. 80.1101, must be used for safety messages by direct-printing
   telegraphy. All messages must be preceded by at least one carriage return, a
   line feed signal, a letter shift signal and the safety signal SECURITE.
   ITU-R Recommendation M.625–3 with Annex is incorporated by reference. The
   Director of the Federal Register approves this incorporation by reference in
   accordance with 5 U.S.C. 552(a) and 1 CFR Part 51. Copies of this standard
   can be inspected at the Federal Communications Commission, 445 12th Street,
   SW., Washington, DC (Reference Information Center) or at the National
   Archives and Records Administration (NARA). For information on the
   availability of this material at NARA, call 202–741–6030, or go to:

   ations.html. The ITU-R Recommendation can be purchased from the
   International Telecommunication Union (ITU), Place des Nations, CH–1211
   Geneva 20, Switzerland.

   (h) Safety communications by direct-printing telegraphy should be in the ARQ
   mode when communicating directly to the Coast Guard or other coast stations
   on channels which they normally guard. Other distress communications,
   including those on simplex channels provided for that purpose, should be in
   the broadcast forward error correction mode. The ARQ mode may subsequently
   be used when it is advantageous to do so.
