The SWS serves as an introduction to the scalar wave application. It is a highly simplified device, which is intended as a desktop device, for the transmission of biological signals. These are transmitted from the transmitter to the receiver, not as in the well-proven SWD in the opposite direction, which reduces the efficiency somewhat. The integrated mp3 player contains pre-stored Rife frequencies.
Book: Documentation (2) on Scalar Wave Medicine included.
