This advanced, 4-channel multifunction electrotherapy system offers a wide range of treatment options in one user-friendly, ergonomic design. It is equipped with a menu-driven, color, touch-screen interface that intuitively groups and displays clinical protocols, guiding the user step-by-step. The “favorites” feature allows user-defined protocols to be stored. The 4 electrotherapy channels can be used in combination (linked) or totally independent, with different protocols running simultaneously.
