Electromagnetic Compatibility and Radio Spectrum Matters (ERM); Technical Characteristics and Test Methods for Analogue Cordless Wideband Audio Devices Using Integral Antennas Operating in the CEPT Recommended 863 MHz to 865 MHz Frequency Range (V1.1.1)
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. The present document applies to wideband cordless audio and in-ear monitoring equipment operating in the CEPT recommended band 863 MHz to 865 MHz using analogue frequency modulation. In some countries this equipment may be used in other frequency bands as specified in their national regulations. The present document does not apply to wideband cordless audio or in-ear monitoring systems employing digital modulation@ Time Division Multiple Access (TDMA)@ frequency hopping and spread spectrum or similar forms of modulation. EN 300 422 [8] applies to consumer radio microphones operating in the CEPT recommended band 863 MHz to 865 MHz with a maximum power level of 10mW. Electromagnetic Compatibility (EMC) requirements are covered by ETS 300 445 [7]. The present document may be used by accredited test laboratories for type testing of the equipment. The performance of the equipment submitted for type testing should be representative of the performance of the corresponding production models. The present document contains instructions for the presentation of equipment for type testing purposes. Power limits recommended in the present document have been chosen to allow maximum simultaneous re-usage of frequency allocations. National regulations on power output may apply up to the limits quoted. The types of equipment covered by the present document are as follows: - cordless headphones; - cordless loudspeakers; - in-ear monitoring; - in-vehicle cordless; - personal cordless.
