Draft Details

The present document specifies technical characteristics and methods of measurements for wireless microphones, 
similar RF audio link equipment, cordless audio (including low power Band II transmitters), in-ear monitoring, cochlear 
implant and assistive listening devices, intended for the transmission of music and speech including the associated 
ancillary equipment in respect of electromagnetic compatibility, as detailed in table 1. 
Technical specifications related to the antenna port and emissions from the enclosure port of the radio equipment are 
out of scope of the present document. Such technical specifications are found in the relevant product standards for the 
effective use of the radio spectrum, see table 1.  
The present document specifies the applicable test conditions, performance assessment and performance criteria for 
wireless microphones, similar RF audio link equipment, cordless audio, in-ear monitoring, ALD and Cochlear Implants 
and associated ancillary equipment. This equipment can use analogue or digital modulation techniques.

present document. 
NOTE 1:  Technical specifications related to conducted emission EMC requirements below 9 kHz on the AC mains 
port of radio equipment are out of scope of the present document. Such technical specifications are 
normally found in the relevant product family standards for AC mains powered equipment (e.g. 
EN 61000-3-2 [i.6] and EN 61000-3-3 [i.7]). 
NOTE 2: The relationship between the present document and essential requirements of article 3.1(b) of
