SSH EN 301 843-4 V1.1.1:2001

Electromagnetic compatibility and Radio spectrum Matters (ERM); ElectroMagnetic Compatibility (EMC) standard for marine radio equipment and services; Part 4: Specific conditions for Narrow-Band Direct-Printing (NBDP) NAVTEX receivers

Scope

The present document together with the EN 301 843-1 [1], covers the assessment of Narrow-Band Direct-Printing
(NBDP) NAVTEX receivers operating in the maritime mobile service, and ancillary equipment in respect of
ElectroMagnetic Compatibility (EMC).
Technical specifications related to the antenna port and emissions from the enclosure port of NAVTEX receivers are not
included in the present document. Such technical specifications are found in the related product standard
ETS 300 065 [4] for the effective use of the radio spectrum.
The present document specifies the applicable test conditions, performance assessment, and performance criteria for
NAVTEX receivers operating in the maritime mobile service, and the associated ancillary equipment.
In case of differences (for instance concerning special conditions, definitions, abbreviations) between the present
document and EN 301 843-1 [1], the provisions of the present document take precedence.
The electromagnetic environment used in the present document to develop the technical specifications encompasses the
electromagnetic environment onboard ships as identified in EN 60945 [5].
