RED software update impact for radio equipment

Assess each update as a product change. First determine whether it can alter an Article 3 requirement: health and safety, EMC, efficient spectrum use, an activated Article 3(3) requirement, or the common-charger information and charging-capability rules for covered equipment.

Annex V requires the technical documentation to identify software or firmware versions that affect compliance with essential requirements. Article 10(5) separately requires series-production procedures to account adequately for changes in product design or characteristics and changes in harmonised standards or other technical specifications. The release record therefore matters even when the supported conclusion is that no retest, declaration change, or notified-body action is needed.

The update record should let a reviewer connect the software release to the radio equipment type placed on the EU market. Keep the release identifier, affected models, affected hardware variants, changed radio or security functions, standards impact, test impact, DoC impact, notified-body impact, approval owner, and release decision.

Annex V is the anchor for the file: it calls for a general product description, conceptual design and manufacturing materials, software or firmware versions affecting compliance, user and installation information, harmonised standards or other technical specifications, the EU declaration, EU-type examination material where applicable, calculations, examinations, and test reports. Article 21 requires the technical documentation to be continuously updated. If the release changes any of those records, update the file instead of relying on release notes alone.

A software update can reopen the conformity-assessment route if the change affects a requirement that was covered by a harmonised standard, a partly applied standard, a technical specification, an EU-type examination certificate, or a full-quality-assurance approval. RED gives presumption of conformity only for the essential requirements covered by OJEU-published harmonised standards or parts of standards.

For Article 3(2) and Article 3(3), the notified-body question is especially important. If relevant OJEU-cited harmonised standards are not applied, are applied only in part, or no such standards exist for the requirement being assessed, Article 17 points the manufacturer to Annex III or Annex IV rather than Annex II for those requirements. For Annex III, modifications to the approved type that may affect conformity or certificate validity require additional approval.

Firmware can affect RED conformity even when no physical component changes. It can alter radio parameters, EMC behavior, safety functions, cybersecurity controls, restrictions, charging behavior, instructions, and the evidence used to place the equipment on the Union market.

Not every update requires a new conformity assessment. The impact decision must explain why the existing Article 3 matrix, standards evidence, technical documentation, DoC, and notified-body records still cover the released configuration, or identify the additional work required before release.

If a released update leaves radio equipment already placed on the market non-conforming, Article 10(11) requires the manufacturer to take the corrective measures needed to bring it into conformity, withdraw it, or recall it if appropriate. Where the equipment presents a risk, the manufacturer must immediately inform the competent national authorities in the Member States where it was made available, with details of the non-compliance, corrective measures, and results.
