Foreword This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Electromagnetic compatibility and Radio spectrum Matters (ERM). For n
26、on EU countries the present document may be used for regulatory (Type Approval) purposes. Equipment compliant with the present document is intended for fitment into road vehicles, therefore it is subject to automotive EMC type approval and has to comply with Commission Directive 2004/104/EC i.4. For
27、 use on vehicles outside the scope of Commission Directive 2004/104/EC i.4 compliance with an EMC directive/standard appropriate for that use is required. The present document is part 1 of a multi-part deliverable covering Electromagnetic compatibility and Radio spectrum Matters (ERM); Short Range D
