Anotácia textu normy ČSN ETSI EN 301489-9-V2.1.1 (875101):

V2.1.1

The present document, together with ETSI EN 301 489-1 [1], covers the assessment of wireless microphones, similar RF audio link equipment, cordless audio, including low power Band II transmitters and in-ear monitoring, intended for the transmission of music and speech, and associated ancillary equipment, in respect of ElectroMagnetic Compatibility (EMC).

Technical specifications related to the antenna port and emissions from the enclosure port of wireless microphones, similar RF audio link equipment, cordless audio and in-ear monitoring are not included in the present document. Such technical specifications are found in the relevant product standards for the effective use of the radio spectrum.

The present document specifies the applicable EMC tests, the test methods, the limits and the performance criteria for wireless microphones, similar RF audio link equipment, cordless audio, in-ear monitoring and associated ancillary equipment. This equipment can use analogue or digital modulation techniques.

Examples of equipment types covered by the present document are given in annex C.

Other types of transmitters or receivers, which are intended for combined use, with either wireless radio microphones, RF audio link equipment, cordless audio and in-ear monitoring will be tested to their appropriate EMC standard.

Low quality speech applications as toy microphones, babyphones etc. operating at frequencies below 50 MHz, occupied bandwidth < 25 kHz and operating according CEPT/ERC/REC 70-03 [i.2], annex 1 are excluded from the present document and are considered in ETSI EN 301 489-3 [i.4].

In case of differences (for instance concerning special conditions, definitions, abbreviations) between the present document and ETSI EN 301 489 1 [1], the provisions of the present document take precedence.

The environmental classification and the emission and immunity requirements used in the present document are as stated in ETSI EN 301 489 1 [1], except for any special conditions included in the present document.

The present document is aimed to cover requirements to demonstrate an adequate level of electromagnetic compatibility
