Foreword This Harmonised European Standard (EN) has been produced by ETSI Technical Committee Electromagnetic compatibility and Radio spectrum Matters (ERM). The present document has been p
37、repared under the Commissions standardisation request C(2015) 5376 final i.7 to provide one voluntary means of conforming to the essential requirements of Directive 2014/53/EU on the harmonisation of the laws of the Member States relating to the making available on the market of radio equipment and
38、repealing Directive 1999/5/EC i.3. Once the present document is cited in the Official Journal of the European Union under that Directive, compliance with the normative clauses of the present document given in table A.1 confers, within the limits of the scope of the present document, a presumption of
39、 conformity with the corresponding essential requirements of that Directive, and associated EFTA regulations.

ETSI ETSI EN 300 720 V2.1.1 (2017-01) 8 1 Scope The present document specifies the minimum technical
42、characteristics required for UHF on board vessels radio equipment and systems operating on frequencies allocated to the maritime mobile services by the ITU Radio Regulations i.1. The present document contains requirements to demonstrate that “. Radio equipment shall be so constructed that it both ef
43、fectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference“ i.3. In addition to the present document, other ENs that specify technical requirements in respect of essential requirements under other parts of article 3 of the Directive 2014/53/EU i.3 may appl
44、y to equipment within the scope of the present document. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
