Recommended separation distances between portable and mobile RF communications equipment and
the Piezosurgery Medical Device
ThePiezosurgeryMedicaldeviceisdesignedtoworkinanelectromagneticenvironmentinwhichRFradiated
disturbancesarekeptundercontrol.ThepurchaseroruserofthePiezosurgeryMedicaldevicecancontribute
topreventelectromagneticinterferencebyensuringaminimumdistancebetweentheRFmobileandcordless
communicationdevice(transmitters)andthePiezosurgeryMedicaldevice,asrecommendedbelow,inrelation
tothemaximumoutputpoweroftheradio-communicationdevices.
