Anotation

IEC 61097-9:2025 specifies the minimum operational and performance requirements and test methods with required test results for transmitters and receivers capable of voice communication and digital selective calling for the GMDSS operating in either the medium frequency band only or in medium and high frequency bands allocated in the ITU Radio Regulations to the Maritime Mobile Service, as required by Chapter IV of SOLAS 1974 as amended. It is based on IMO resolution MSC.512(105) and takes account of Recommendation ITU-R M.493 for digital selective calling including the automatic connection system. This second edition cancels and replaces the first edition published in 1997. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the text has been updated to incorporate the provisions of the new IMO performance standards given in Resolution MSC.512(105) and new ITU-R recommendations given in M.493-16. These provisions in particular add new requirements for reception of maritime safety information and for the automatic connection system; b) the provisions for digital selective calling which were previously in IEC 61097-3 have been incorporated; c) the provisions for watch keeping receivers which were previously in IEC 61097-8 have been incorporated; d) new requirements have been added for software maintenance in 4.10 in support of IMO recommendations; e) new Annex A, Annex B and Annex C have been added for digital selective calling; f) new Annex D and Annex G have been added for bridge alert management; g) new Annex E and Annex I have been added for maritime safety information; h) a new Annex F has been added for the automatic connection system; i) a new Annex H has been added for equipment manuals; j) a new Annex J has been added for remote control operation; k) previous Annex A, Annex B and Annex C have been deleted as they are no longer relevant.
