Foreword This Harmonized European Standard (EN) has been produced by ETSI Technical Committee Electromagnetic compatibility and Radio spectrum Matters (ERM). The present document has been produced by ETSI in response to mandate M/284 issued from the European Commission under Directive 98/34/EC [i.1] as amended by Directive 98/48/EC [i.1]. The title and reference to the present document are intended to be included in the publication in the Official Journal of the European Union of titles and references of Harmonized Standard under the Directive 1999/5/EC [i.2]. See article 5.1 of Directive 1999/5/EC for information on presumption of conformity and Harmonised Standards or parts thereof the references of which have been published in the Official Journal of the European Union. The requirements relevant to Directive 1999/5/EC [i.2] are summarised in annex A. Equipment compliant with the present document can be intended for fitment into road vehicles, therefore it is subject to automotive EMC type approval and Directive 95/54/EC [i.3]. For use on vehicles outside the scope of
Directive 95/54/EC [i.3], compliance with an EMC directive/standard appropriate for that use is required.

The provider shall declare the frequency ranges, the range of operating conditions and power requirements as applicable, to establish the appropriate test conditions. Additionally, technical documentation and operating manuals, sufficient to make the test, shall be supplied. 4.1.1 Choice of model for testing The provider shall provide one or more samples of the equipment, as appropriate for testing. Stand-alone equipment shall be offered by the provider complete with any ancillary equipment needed for testing. If an equipment has several optional features considered not to affect the RF parameters, then the tests need only to be performed on the equipment configured with the combination of features considered to be the most complex, as proposed by the provider and agreed by the test laboratory. Where practicable, equipment offered for testing shall provide a 50 Ω connector for conducted RF power level measurements. In the case of a dedicated integral antenna equipment, if the equipment does not have an internal permanent 50 Ω connector, then it is permissible to supply a second sample of the equipment with a temporary antenna connector fitted to facilitate testing. The performance of the equipment submitted for testing shall be representative of the performance of the corresponding production model. The equipment may contain digital circuit elements, radio circuit elements and other elements whose performance is not covered by the present document. These elements of the equipment shall meet the appropriate performance requirements for those components, as specified in other standards. An ITS device which is combined with other system(s) should meet at least the requirements of the present document (for the elements o
