Foreword
This European Standard (Telecommunications series) has been produced by ETSI Technical Committee
Electromagnetic compatibility and Radio spectrum Matters (ERM).
Every EN prepared by ETSI is a voluntary standard. The present document may contain text concerning conformance
testing of the equipment to which it relates. This text should be considered as guidance only and does not make the
present document mandatory.
Annex A provides normative specifications concerning radiated measurements.
Annex B provides a graphic representation of the equipment and frequencies for the testing of single and
multi frequency equipment.
Annex C provides informative parameters on the receiver part, which are intended to give guidance to manufacturers.
The present document is part 1 of a multi-part standard covering analogue cordless wideband audio devices using
integral antennas operating in the CEPT recommended 863 MHz to 865 MHz frequency range, as identified below:
Part 1: "Technical characteristics and test methods";
Part 2: "Harmonized EN under article 3.2 of the R&TTE Directive".
National transposition dates
Date of latest announcement of this EN (doa): 31 October 2000

Introduction
In preparing the present document, much attention has been given to assure a low interference probability, while at the
same time allowing a maximum flexibility and service to the end-user.
The present document provides the necessary parameters for equipment to obtain common approval throughout Europe.
Common technical specifications and harmonized frequency allocations are expected to reduce the present problems of
interference and illegal use.
The present document is a type-testing standard based on spectrum utilization parameters and does not include
performance characteristics that may be required by the user or requirements for interfacing equipment.

The present document is intended to specify the minimum performance and the methods of measurement of, wideband
cordless audio equipment in the range 25 MHz to 2 000 MHz and Consumer Radiomicrophones & In ear monitoring
equipment in the range 863 MHz to 865 MHz, as specified in the scope. Consumer radiomicrophones and in -ear
monitoring equipment may be tested to either EN 300 422 [8] for equipment with maximum occupied
bandwidth < 200 kHz or to the present document for equipment with maximum occupied bandwidth > 200 kHz with due
consideration of power and operating frequency.
Type test measurements should be performed in one of the accredited test laboratories, accepted by the various national
regulatory authorities in order to grant type approval, provided the national regulatory requirements are met. This is in
compliance with CEPT/ERC/REC 01-06 [1] and CEPT/ERC/DEC(97)10 [2].
In addition, national administrations may accept a "certificate of conformity" based on a type test report. If equipment
available on the market is required to be checked, it should be tested in accordance with the methods of measurement
specified in the present document.

1 Scope
The present document covers the minimum characteristics considered necessary in order to make the best use of the
available frequencies. It does not necessarily include all the characteristics that may be required by a user, nor does it
necessarily represent the optimum performance achievable.
Cordless audio devices covered within the present document are considered by definition short-range devices, the power
limits for frequency bands will be found in the current version of CEPT/ERC/REC 70-03 [6] (or national regulations).
The present document applies to wideband cordless audio, consumer radiomicrophones and in-ear monitoring
equipment using either 300 kHz bandwidth analogue modulation or 300 kHz, 600 kHz or 1 200 kHz digital FDMA
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.
Consumer audio equipment intended for audio and voice operating below 50 MHz and using narrow band modulation
are considered and tested according to EN 300 220 [10].
Electromagnetic Compatibility (EMC) requirements are covered by EN 301 489-9 [7].
The types of equipment covered by the present document are as follows:
- cordless headphones;
- cordless loudspeakers;
- consumer radiomicrophones;
- in-ear monitoring;
- in-vehicle cordless;
- personal cordless;
- broadband multichannel audio systems.
