ETSI - EN 300 422-2
Electromagnetic compatibility and Radio spectrum Matters (ERM); Wireless microphones in the 25 MHz to 3 GHz frequency range; Part 2: Harmonized EN covering the essential requirements of article 3.2 of the R&TTE Directive
|Publication Date:||1 January 2015|
The present document applies to equipment operating on radio frequencies between 25 MHz and 3 GHz, using analogue, digital and hybrid (using both analogue and digital modulation) modulation.
The present document applies to the following radio equipment types:
- Professional Wireless Microphone Systems (PWMS);
- in ear monitoring systems;
- consumer radio microphones;
- tour guide systems; and
- Assistive Listening Devices (Aids for the handicapped) comprising personal and public hearing aid systems.
The maximum power recommended for equipment covered by the present document is 250 mW for radio microphones and 500 mW for public hearing aids in the 169,4 MHz to 169,8125 MHz band (erp below 1 GHz and eirp above 1 GHz).
The present document also covers radio microphones used in the 863 MHz to 865 MHz band, with a maximum power of 10 mW.
The present document is intended to cover the provisions of Directive 1999/5/EC [i.1] (R&TTE Directive):
Article 3.2, which states that "..... radio equipment shall be so constructed that it effectively uses the spectrum allocated to terrestrial/space radio communications and orbital resources so as to avoid harmful interference".
In addition to the present document, other ENs that specify technical requirements in respect of essential requirements under other parts of Article 3 of the R&TTE Directive may apply to equipment within the scope of the present document.
