ElectroMagnetic Compatibility and Radio Spectrum Matters (ERM); Analogue cordless wideband audio devices using integral antennas operating in the CEPT recommended 863 MHz to 865 MHz frequency range; Part 1: Technical characteristics and test methods

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.
