For Article 3(1)(a), assess all intended operating conditions and reasonably foreseeable conditions of use. Do not limit the analysis to electrical voltage bands: RED imports the Low Voltage Directive safety objectives without its voltage limits. Depending on the product, evidence may need to address electrical, thermal, mechanical, chemical, fire, battery, acoustic, and radio-frequency exposure risks.
For Article 3(1)(b), document the EMC route, standards or other specifications used, immunity and emissions evidence, operating modes, ports, cables, accessories, and installation conditions for the radio equipment configuration being declared. EMC evidence does not replace Article 3(2) spectrum evidence.
For Article 3(2), document the radio technology, operating bands, transmitter emissions, receiver performance, intended installation and antenna conditions, and spectrum standards used. If a cited harmonised standard is not applied, is only partly applied, does not cover the configuration, or does not exist, Article 17 removes internal production control for the affected Article 3(2) requirement; use Annex III EU-type examination plus conformity to type or Annex IV full quality assurance.
