35、5 0045237 003 Page 9 ETS 300 373: August 1995 Foreword This European Telecommunication Standard (ETC) has been produced by the Radio Equipment and Systems (RES) Technical Committee of the European Telecommunications Standards Institute (ETSI). The ETS sets out the minimum requirements for Medium Fre
36、quency (MF) and Medium and High Frequency (MFiHF) equipment on board ships, operating in the maritime mobile MF and HF radio services. Every ETS prepared by ETSI is a voluntary standard. This ETS contains text concerning conformance testing of the equipment to which it relates. This text should be c
37、onsidered only as guidance and does not make this ETS mandatory. Transposition dates Date of adoption of this ETS: Date of latest announcement of this ETS (doa): 26June1995 30 November 1995 Date of latest publication of new National Standard or endorsement of this ETS (dop/e): 31 May 1996 Date of wi

39、mum requirements for radio transmitters and receivers, for use on ships, operating in either the Medium Frequency (MF) only or in the Medium and High Frequency (MF/HF) bands allocated in the Intemational Telecommunications Union (ITU) Radio Regulations i, to the Maritime Mobile Service (MMS). This E
40、TS refers to equipment for one or more of the following: - Single SideBand (SSB) modulation for telephony transmission and reception; (J3E) - Frequency Shift Keying (FSK) or SSB modulation of a keyed sub-camer to transmit and receive Digital Selective Calling (DSC) signals in accordance with ITU-R R
41、ecommendation 493-5 5. This ETS also refers to radio equipment, which is not integrated with the DSC encoder or decoder, but defines the interfaces with such equipment. NOTE: The requirements for integrated equipment may be found in other relevant ETSs. The tests in this ETS are applicable to receiv
42、ers for operating on all frequencies in the bands 1 605 kHz to 4 O00 kHz or 1 605 kHz to 27,5 MHz as allocated in the Radio Regulations l, to the MMS. Other spot frequency receivers should meet all the requirements of this ETS and other relevant standards as applicable for the frequencies and modes
43、provided. This ETS includes the International Maritime Organisation (IMO) and ITU requirements included in the relevant provisions of the Radio Regulations 111, the Intemational Convention for the Safety Of Life At Sea (SOLAS) 3, and the IMO Resolutions A.421(XI), A.610(15), A.613(15), and A.694(17)
44、 4. If the equipment, or parts of it, are designed in such a manner that they can be used for other categories of maritime radiocommunication (e.g. Morse telegraphy or NBDP (ETS 300 067) 9), those parts of the equipment should fulfil the relevant requirements of the appropriate standards for the ser
45、vice) in question e.g. ETS 300 067 QI. 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
