§  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 § 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
   § 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 § 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:

   r_locations.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.
