Annotation of standard text ČSN ETSI EN 300422-3-V2.1.1 (875032):
V2.1.1 The present document specifies the technical characteristics and methods of measurement for the following types of equipment: 1) Assistive Listening Devices; 2) Radio Microphones; 3) In-ear Monitoring Systems; 4) WMAS (Wireless Multichannel Audio Systems; 5) Tour Guide Systems; with Class C receivers which have significantly 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 C receivers will support the operation of fewer wireless audio channels in a given amount of spectrum than Class A or Class B 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 EC Decision 2005/928/EC [i.9] and EC Decision 2006/771/EC [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 - EC Decision 2014/641/EU [i.11]. Unless otherwise stated in the EC SRD Decision, ECC Decision or National Interfaces, Radio Microphones can be subject to individual licence
