ElectroMagnetic Compatibility and Radio Spectrum Matters (ERM); Cordless audio devices in the range 25 MHz to 2 000 MHz; Consumer radio microphones and in-ear monitoring systems operating in the CEPT harmonized band 863 MHz to 865 MHz; 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 cordless audio, consumer radio microphones and in ear monitoring equipment using
either 300 kHz bandwidth analogue modulation or 300 kHz, 600 kHz or 1200 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 radio microphones;
- in-ear monitoring;
- in-vehicle cordless; personal cordless;
- broadband multi channel audio systems.
