The Sys-Stim 206 Stimulator is a muscle stimulator that can deliver the kind of performance and safety that only a high quality microprocessor-based stimulator can, at a very small price. With four preset stimulation modes plus Surge and Reverse Polarity, you'll be able to choose the most beneficial waveform for different treatments and muscle groups. Each is balanced for maximum patient comfort. Since the Sys-Stim 206 overcomes current breakdown caused by skin resistance, the waveform you select is always the one get. For added flexibility, the Sys-Stim 206 is compatible with any Sonicator for effective combination therapy. Features: Go/Hold keys permit operator to initiate or suspend treatment with one touch. Membrane Entry Panel simplifies treatment control. Timer Entry Selector sets treatment time from 1 to 29 minutes. Timer bypass initiates a continuous run. LED Display indicates output intensity in peak volts or milliamps, and treatment time remaining. Treatment Mode Selectors include four preset waveforms plus Surge and Reverse Polarity, enabling operator to choose the optimum waveform for each treatment and muscle group. Intensity Control allows operator to vary output voltage to the patient during treatment. Pulse Frequency Control permits user to vary the repetition of pulses applied to the patient from 1 to 83 pps, in all modes except surge.
