+## Legal Disclaimer – Radio Equipment Directive (RED) & Usage Limitations
+
+This project and its documentation relate **exclusively to the Passive Optical Network (PON) layer** of optical network devices.  
+We **do not access, modify, or interact with any radio components, wireless interfaces, or transmitters**.
+
+As such, the activities described here are **not intended to fall under the scope** of the EU Radio Equipment Directive (RED)
+(**Directive 2014/53/EU**) or the associated **Delegated Regulation (EU) 2022/30** on cybersecurity for internet-connected radio devices.
+
+However, any modification involving radio hardware **may trigger RED applicability**. Users are advised to assess regulatory obligations accordingly.
+
+Modified devices are strictly intended for **private, domestic, and non-commercial use** in **experimental contexts only**.  
+They must **not be used in production environments**, nor in **commercial, enterprise, or SOHO scenarios**, and **must not be resold or deployed for profit**.
+
+This project makes **no claim of regulatory compliance** and assumes **no responsibility** for damages, legal issues, or security risks arising from use or redistribution.
