BioMedical Life Systems is proud to introduce its new generation in Electro-Therapy Devices, the Impulse TENSD5 Digital TENS Device. The new look of the device incorporates a Clam Shape design that when closed, covers the LCD Screen and Control Buttons. The inside flip top cover includes an instruction diagram to guide the user through five modes of operation; constant, width modulation, rate modulation and two different types of burst. A timer allows the patient to use the device for a specified period of time and a low battery indicator light illuminates when the AA batteries need to be changed. If the device is not correctly attached to the patient, the amplitude does not increase. Includes Lead Wires 4 Electrodes
