ThecompliancelevelsintheISMfrequencybandsbetween150kHzand80MHzandinthefrequencyrange80
MHz to 2.5 GHz are intended to decrease the likelihood that mobile/portable communications equipment could
causeinterferenceifitisinadvertentlybroughtintopatientareas.Forthisreason,an
additional factor of 10/3 Is used in calculating the recommended separation distance for transmitters in these
frequency ranges.
