    Abstract - (Show below) - (Hide below)

    Applies to systems used in searching for and/or finding people hidden by avalanches, for rescue. The avalanche beacons shall consist of a transmitter and receiver part. The two beacons covered are type 1 single frequency (457 kHz) and type 2 double frequency (2,275 kHz and 457 KHZ) temporary type, compatible with beacons having frequency of 2,275 kHz. Intended to ensure the practical interoperability and reliability of products from different manufacturers.
