Specifications Of The Tests For The Immunity Of The Accessible Parts Of The Casing To The Wireless Rf Communications Device - Mectron PIEZOSURGERY WHITE Mode D'emploi Et D'entretien

8.1.4 Specifications of the tests for the Immunity of the Accessible
Parts of the Casing to the Wireless RF Communications Device
PIEZOSURGERY® white is designed to operate in an electromagnetic environment in which
radiated RF disturbances are under control. The customer or the user of PIEZOSURGERY® white
can help prevent electromagnetic interference by ensuring a minimum distance between the
mobile and portable RF (transmitters) communication devices and PIEZOSURGERY® white, as
recommended, in relation to the maximum output power of radiocommunications equipment.
