    SLEEP screen Some protocols may include a SLEEP segment. During this segment, the device does not provide stimulation, but the timer is counting down to the next treatment. This function is used if a clinician wants to create a protocol where the device treats for a specifi ed amount of time, stops, then treats again, without the patient having to turn the device on and off.

  • Page 20: Electrode Use And Care

    Electrode Use and Care WARNING: This product should be used only under the direct super- vision of a registered healthcare practitioner. Product use should be in accordance with the directions and specifi cations of the stimulation device. Improper use of this or any electrode may result in a patient burn. Due to the potential for causing skin burns, devices must be limited to 0.25W per cm .

  • Page 21: Cradle/Modem

    How many times should I use these reusable electrodes?  Electrode life varies due to skin condition, skin preparation, storage, climate and care but for most patients electrodes will last for approx- imately 7-10 applications and removals.  If your electrodes start to dry out, gently rub a few drops of water into the gel on the electrode to remoisten.

    Waveform Diagrams Figure 1 – HVPC stimulation This drawing shows the output waveform in the HVPC stimulation mode at maximum amplitude (330V). The waveform is shown with a purely resistive load of 500 ohms. The signal repeats at a period of time equal to the recip- rocal of the rate.
  • Page 33 Figure 2 – Premodulated IF stimulation This drawing shows the output waveform in the single-channel premodu- lated IF stimulation mode at maximum amplitude (50mA). The waveform is shown with a purely resistive load of 500 ohms. The two signals created in two-channel mode are internally added together and output on a single channel.
  • Page 34 Figure 3 – Two-channel IF stimulation This drawing shows the output waveform in the two-channel IF stimula- tion mode at maximum amplitude (50mA). The waveform is shown with a purely resistive load of 500 ohms. Ch. 1 is shown; Ch. 2 is identical except that the period is slightly less since the rate is slightly greater.
