21、 Electromagnetic compatibility and Radio spectrum Matters 0. The present document corrects a technical error that was identified in ETS 300 718 (1997). The requkernent for the maximum weight of the apparatus (subclause 4.2.1) has been deleted. It is intended that this TS should be used as a basis fo

22、r a future revision of ETS 300 718 (1997). I n t rod uct i o n There are currently two frequency allocations for the radio location of avalanche victims: - 2275Hz;and - 457kHz. It is expected that the allocation at 2 275 Hz will be removed after a tramition penod. The present document therefore cove

23、rs duai-frequency equipment and equipment intended to operate on 457 ICHZ only. It is the purpose of the present document to ensure the practical interoperability and reliability of products from different manufacturers. ETSI 7 TS 100 718 V1.l.l (1999-01) 1 Scope The present document covers requirem

24、ents for avalanche beacons. Avalanche beacons are radio location systems used for searching for andor ndiug avalanche victims, for the purpose of direct rescue. These systems comprise a transmitter as well as a receiver part. The present document distinguishes between two types of beacons: - type i:

25、 single frequency beacons (457 a); - type 2: double frequency beacons (2 275 Hz and 457 a) temporary type, compatible to beacons with frequency 2 275 Hz. 2 Ref e rences The following documents contain provisions which, through reference in this text, constitute provisions of the present doment. Refe

26、rences are either specific (identified by date of publication, edition number, version number, etc.) or non-specific.
