    8.Definition and parameters Frequency modulation program FM determines in what time relations the base frequency modulation in the set up range occurs. The FM program describes the duration of lowest base frequency, time of increase to its highest value and time of falling to its lowest value. If SPECTRUM value is set up at 0 Hz, it is not possible to use frequency modulation program.

  • Page 40: Interferential Currents

    As opposed to the classic technique of generating interferential currents within patient’s tissue (frequency interference), with the Etius unit the internal modulation process has been transferred to the inside of the unit. This technology causes generation of interference field occupying much space (the therapeutic current passes larger tissue space than with the classic method), interference occurs even in case of not very precise electrode application, which simplifies the treatment method.
