适用范围

The present document specifies the technical characteristics and methods of measurement for the following types of equipment: 1) Assistive Listening Devices (ALDs); 2) Radio Microphones; 3) In-Ear Monitoring Systems; 4) Wireless Multichannel Audio Systems (WMAS); 5) Tour Guide Systems; with Class B receivers which have reduced performance requirements with respect to sensitivity@ adjacent channel selectivity@ and receiver blocking compared to those with Class A receivers. It does not necessarily include all the characteristics that may be required by a user@ nor does it necessarily represent the optimum performance achievable. Equipment with Class B receivers will support the operation of fewer wireless audio channels in a given amount of spectrum than Class A receivers. The present document applies to equipment operating on radio frequencies up to 3 GHz (as shown in table 1) using analogue@ digital and hybrid (using both analogue and digital) modulation. The maximum power recommended for equipment covered by this multi-part deliverable is 250 mW for radio microphones and 10 mW for ALDs. An exception to this are the Public Hearing Aids defined in the CEPT Report 004 [i.7] and subsequent ECC [i.9] and EC Decisions [i.8] on the ex ERMES band (169@4 MHz to 169@8125 MHz) where 500 mW is defined. The present document covers the essential requirements of Article 3.2 of Directive 2014/53/EU under the conditions identified in annex A. The present document also covers radio microphones used in the 863 MHz to 865 MHz band@ with a maximum power of 10 mW. Electromagnetic Compatibility (EMC) requirements are covered by ETSI EN 301 489-9 [i.4]. National regulations on: 1) maximum power output; 2) licensing status; will take precedence or those detailed in the latest version of: ? EC Decision 2005/928/EC [i.9]; ? ECC/DEC/(05)02 [i.10]; ? the EC SRD Decision [i.8]; or ? CEPT/ERC/REC 70-03 [i.6]@ annex 10 (see http://www.erodocdb.dk/); ? EC Decision 2014/641/EU [i.11].
