Foreword
This draft Harmonised European Standard (EN) has been produced by ETSI Technical Committee Electromagnetic
compatibility and Radio spectrum Matters (ERM), and is now submitted for the combined Public Enquiry and Vote
phase of the ETSI standards EN Approval Procedure.
The present document has been prepared under the Commission's standardisation request C(2015) 5376 final [i.1] 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 repealing
Directive 1999/5/EC [i.2].
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 conformity with the corresponding essential requirements of that Directive, and associated
EFTA regulations.
Proposed national transposition dates
Date of latest announcement of this EN (doa): 3 months after ETSI publication
Date of latest publication of new National Standard
or endorsement of this EN (dop/e): 6 months after doa
Date of withdrawal of any conflicting National Standard (dow): 18 months after doa

Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and
"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of
provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.

1 Scope
The present document specifies the minimum requirements for transmitters, receivers and transceivers fitted with
external antenna connectors, used as coast stations, operating in the VHF band of the maritime mobile service. This
includes:
- equipment operating under local or remote control;
- equipment operating on 12,5 kHz or 25 kHz channel spacing;
- equipment capable of analogue speech, Digital Selective Calling (DSC), or both;
- equipment operating in Simplex, Semi-Duplex (Half Duplex) and Duplex modes;
- equipment which may consist of more than one unit;
- equipment which may be single-channel or multi-channel;
- equipment operating on shared radio sites;
- equipment operating in isolation from other radio equipment.
Where the equipment is not intended for DSC operation, only those clauses relevant to non-DSC tests are applicable.
The present document covers the essential requirements of article 3.2 of Directive 2014/53/EU [i.2] under the
conditions identified in annex A.

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 prepared under the Commission's standardisation request C(2015) 5376 final [i.1] 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 repealing Directive 1999/5/EC [i.2]. 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 conformity with the corresponding essential requirements of that Directive, and associated EFTA regulations.

ETSI ETSI EN 301 929 V2.1.1 (2017-03) 8 1 Scope The present document specifies the minimum requirements for transmitters, receivers and transceivers fitted with external antenna connectors, used as coast stations, operating in the VHF band of the maritime mobile service. This includes: - equipment operating under local or remote control; - equipment operating on 12,5 kHz or 25 kHz channel spacing; - equipment capable of analogue speech, Digital Selective Calling (DSC), or both; - equipment operating in Simplex, Semi-Duplex (Half Duplex) and Duplex modes; - equipment which may consist of more than one unit; - equipment which may be single-channel or multi-channel; - equipment operating on shared radio sites; - equipment operating in isolation from other radio equipment. Where the equipment is not intended for DSC operation, only those clauses relevant to non-DSC tests are applicable. The present document covers the essential requirements of article 3.2 of Directive 2014/53/EU [i.2] under the conditions identified in annex A. 2 References 2.1 Normative references References are specific, identified by date of publication and/or edition number or version number.
