Foreword
This European Telecommunication Standard (ETS) has been produced by the Radio Equipment and
Systems (RES) Technical Committee of the European Telecommunications Standards Institute (ETSI).
This ETS defines the minimum technical characteristics required for portable VHF radio telephones
operating in survival craft, and optionally on board ships at sea, in certain frequency bands allocated to the
Maritime Mobile Service (MMS). It also incorporates the requirements detailed in the Radio Regulations,
International Convention for the Safety Of Life At Sea SOLAS 1974 (as amended in 1988) [3] and the
relevant recommendations of the International Maritime Organization.
Every ETS prepared by ETSI is a voluntary standard. This ETS contains text concerning type approval of
the equipment to which it relates. This text does not make this ETS mandatory in its status as a standard.
However, this ETS can be referenced, wholly or in part, for mandatory application by decisions of
regulatory bodies.

1 Scope
This ETS states the minimum technical characteristics required for portable VHF radiotelephones
operating in the bands between 156 MHz and 174 MHz allocated to the Maritime Mobile Services by the
Radio Regulations (see Radio Regulations, Appendices 18 [1] and 19 [2]) and suitable for use in survival
craft and, optionally, on board ships at sea. The requirements detailed in the Radio Regulations,
International Convention for the Safety Of Life At Sea SOLAS 1974 [3], and the International Maritime
Organization Resolutions A.694(17) [5] and A.762(18) [4] are incorporated in this ETS.
2 Normative references
This ETS incorporates by dated or undated reference provisions from other publications. These normative
references are cited at the appropriate places in the text and the publications are listed hereafter. For
dated references, subsequent references to or revisions of any of these publication apply to this ETS only
when incorporated in it by amendment or revision. For undated references the latest edition of the
publication referred to applies.
