Simple to understand instructions guide the user through all of the device’s operations. Five pre-programmed protocols, three of which are incontinence therapies, ensure ease of use. With two waveforms to choose from, asymmetrical or symmetrical biphasic square waves, the device can be used as a Muscle Stimulator and/or a TENS device. The unit has three types of stimulation, continuous, cycled or reciprocating and adjustable pulse rate and pulse width. The patient lock system, when activated, allows parameters to be set and locked preventing the patient from changing the settings. When the patient lock is deactivated, the patient compliance meter is displayed showing the cumulative time the device has been used. The timer allows the patient to set the duration of each therapy session. The two-channel device incorporates touch proof design and operates on four AA batteries. Weight: 8 oz. Includes carrying case and instructions. 5-year limited warranty.
