Diadynamic currents
The device generates unipolar low-frequency currents or a medium-frequency carrier currents, whose envelope
corresponds to the traditional diadynamic currents. There are no significant therapeutic differences between
such an approach to diadynamic currents generation and traditional method. However, because of applying
medium frequency current, the unpleasant patient’s sensations during the procedure and the electrochemical
effect are reduced. With this method of signal generation, it should be taken into consideration that a higher
amplitude has to be set in order to evoke a certain level of patient’s sensation, in comparison to traditional
diadynamic currents.

Polarization
NOR
For such polarization setting red plug is a positive
electrode, and black plug is a negative electrode.
REV
For such polarization setting red plug is a negative
electrode and black plug is a positive electrode.
Warning means that such a setting is the reverse
of commonly accepted way of marking polarity.
