scope:

The present document states the minimum 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 International Telecommunications Union (ITU) Radio Regulations [6], to the Maritime Mobile Service (MMS).

The present document includes the International Maritime Organization (IMO) and ITU requirements included in the relevant provisions of the Radio Regulations [6], the International Convention for the Safety Of Life At Sea (SOLAS) [i.1], the IMO Resolutions A.694(17) [i.3] and A806 (19) [i.2] and is primarily intended to specify equipment suitable for fitting to ships subject to the SOLAS convention and complying with the European Marine Equipment Directive [i.12].

The present document 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-carrier to transmit and receive Digital Selective Calling (DSC) signals in accordance with Recommendation M.493-13 ITU-R [i.4].

The present document also refers to radio equipment, which is not integrated with the DSC encoder or decoder, but defines the interfaces with such equipment.

NOTE 1: The requirements for integrated equipment may be found in other relevant ENs.

NOTE 2: The requirements for other modes of operation may be found in other relevant ENs.

The tests in the present document are applicable to equipment operating on all frequencies in the bands 1 606,5 kHz to 4 000 kHz or 1 606,5 kHz to 27,5 MHz as allocated in the Radio Regulations [6], to the MMS.

The present document does not address the testing of ancillary equipment on a stand-alone basis, i.e. separately from the radio equipment with which it is to be used.

NOTE 3: The EMC requirements and requirements for cabinet radiation for ancillary equipment are found in EN 301 843-5 [i.5], clause 7.
