Press the PULSE RATE arrow keys to the left-side of the Treatment Screen to change the PULSE RATE. Press the
PULSE DURATION arrow keys to the right-side of the Treatment Screen to change the PULSE DURATION. Press
the MODE toggle key and select TIME to return the TIME display. However, if you make no key presses for 10
seconds, the display automatically returns to the TIME display. The ranges and default settings for pulse duration
(width) and pulse rate are listed later in this section.
7. Raise the INTENSITY to the desired level.
Set the intensity by pressing the INTENSITY arrow keys located on the right-side of the Treatment Display Screen.
Increasing the intensity sends current directly to the patient. Intensity can be decreased by pressing the down arrow key,
Before selecting the intensity setting for an individual patient, see section entitled “Electrotherapy Usage Cautions”
for recommended intensity settings. Also see the section of this manual entitled “Contraindications, Warnings, and
Precautions” for specific precautions when treating any conditions contributing to loss of sensation, or any time the
patient cannot feel the electrical stimulation.
The intensity, pulse rate, and pulse duration must all be considered together when setting up the treatment as all
three factors affect patient comfort. It may be necessary to adjust one or more of these parameters somewhat after
the initial settings are selected to find the best settings for a given treatment and patient.
8. For co-contraction or reciprocal treatments, select the SECOND CHANNEL and set the INTENSITY.
Intensity is set for each channel separately. For co-contraction or reciprocal treatments, Set the intensity for the
first channel. Press START. The device will automatically select the second channel. Set the intensity for the second
channel. When setting intensity, only the channel with the solid GREEN light is affected. The first channel will be
illuminated in YELLOW.
9. Press START
When you press START the treatment timer begins counting down. If the intensity is not set before pressing START,
the treatment will not begin until the intensity is set. For Reciprocal and Co-contraction treatments, the intensity
must be set for each channel separately.
10. SAVE DEFAULTS
If this treatment setup is the most common Biphasic or Russian treatment setup you use, save the treatment
parameters as your defaults. After setting up the treatment, press and hold the START key until a tone sounds
indicating the treatment parameters have been saved. The next time you select this modality, the saved parameters
will be selected automatically.
11. MODIFY Settings
While the treatment is in progress, the treatment settings can be modified. Carefully observe the channel indicator
lights when modifying a treatment. When a channel’s light is illuminated GREEN, the current treatment parameters
for that channel are displayed. Any changes made to the parameters will affect only the channel that is illuminated in
GREEN. Use the toggle key to display the parameters of another channel in order to modify parameters.
During a Biphasic or Russian treatment you may make the following modifications:
• CONTRACTION/REST cycle.
