ETSI EN 300 422-1 covers the minimum characteristics considered necessary in order to make the best use of theavailable frequency spectrum for wireless microphones and Aids for the hearing impaired.
The present document specifies the minimum performance requirements and the methods of measurement of AssistiveListening Devices, radio microphones and in-ear monitoring systems. It does not necessarily include all thecharacteristics that may be required by a user, nor does it necessarily represent the optimum performance achievable.
The present document applies to equipment operating on radio frequencies between 25 MHz and 3 GHz (as shown intable 1) using analogue, digital and hybrid (using both analogue and digital) modulation.
The maximum power recommended for equipment covered by the present document is 250 mW for radio microphonesand 10 mW for ALDs.
An exception to this are the Public Hearing Aids defined in the CEPT Report 004 [i.9] and subsequent ECC [i.11] andEC Decisions [i.10] on the ex ERMES band (169,4 MHz to 169,8125 MHz) where 500 mW is defined.
The present document also covers radio microphones used in the 863 MHz to 865 MHz band, with a maximum powerof 10 mW.
