Foreword
This Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical Committee
Electromagnetic compatibility and Radio spectrum Matters (ERM).
The present document has been produced by ETSI in response to a mandate from the European Commission issued
under Council Directive 98/34/EC(as amended) laying down a procedure for the provision of information in the field of
technical standards and regulations.
The present document is intended to become a Harmonized Standard, the reference of which will be published in the
Official Journal of the European Communities referencing the Directive 1999/5/EC [1] of the European Parliament and
of the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual
recognition of their conformity ("the R&TTE Directive").
Technical specifications relevant to Directive 1999/5/EC are given in annex
The present document is part 2, of a multi-part deliverable covering Cordless audio devices in the range 25 MHz to
2 000 MHz, as identified below:
Part 1: "Technical characteristics and test methods";
Part 2: "Harmonized EN covering essential requirements of article 3.2 of the R&TTE Directive".
National transposition dates
Date of adoption of this EN: 21 July 2006
Date of latest announcement of this EN (doa): 31 October 2006
Date of latest publication of new National Standard
or endorsement of this EN (dop/e): 30 April 2007
Date of withdrawal of any conflicting National Standard (dow): 30 April 2008
Introduction
The present document is part of a set of standards developed by ETSI and is designed to fit in a modular structure to
cover all radio and telecommunications terminal equipment within the scope of the R&TTE Directive. The modular
structure is shown in EG 201 399.

1 Scope
The present document covers Cordless audio devices considered by definition short-range devices.
• the present document applies to cordless audio consumer radio microphones, in ear monitoring equipment
using either 300 kHz bandwidth analogue modulation; or
• 300 kHz, 600 kHz; or
• 1200 kHz digital FDMA modulation; and
• Band II LPD (low power devices) using 200 kHz bandwidth and analogue modulation.
The frequency bands for this equipment may differ from country to country as specified in their national regulations.
All equipment is intended to be used with integral antennas.
The types of equipment covered by the present document are as follows:
• cordless headphones;
• cordless loudspeakers;
• consumer radio microphones;
• in-ear monitoring;
• in-vehicle cordless;
• personal cordless;
• broadband multi channel audio systems;
• Band II LPD.
The present document is intended to cover the provisions of Directive 1999/5/EC [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.
NOTE: A list of such ENs is included on the web site http://www.newapproach.org.

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
artificial antenna: tuned reduced-radiating dummy load equal to the nominal impedance specified by the applicant
integral antenna: antenna, with or without a connector, designed as, and declared as by the manufacturer, an
indispensable part of the equipment
integral antenna for Band II LPD only: permanent fixed antenna, which may be built-in, designed as an
indispensable part of the equipment
necessary bandwidth: is, for a given class of emission, the width of the frequency band which is just sufficient to
ensure the transmission of information at the rate and with the quality required under specified conditions
NOTE: However, the necessary bandwidths of most digital modulation formats are presently not referred to
ITU-R Recommendations of SM series.
port: any connection point on or within the Equipment Under Test (EUT) intended for the connection of cables to or
from that equipment
radiated measurements: measurements that involve the absolute measurement of a radiated electromagnetic field
spurious emission: emission on a frequency or frequencies which are outside the necessary bandwidth and the level of
which may be reduced without affecting the corresponding transmission of information. Spurious emissions include
harmonic emissions, parasitic emissions, intermodulation products and frequency conversion products.
