8. For co-contraction or reciprocal treatments, select the SECOND CHANNEL and set the
INTENSITY for this channel.
Intensity is set for each channel separately. Press the Channel Toggle key to select the
second channel. When you are setting intensity, only the channel with the solid green
light is affected. If you wish to select a channel which has a YELLOW-colored light,
press the Channel Toggle key until that channels’ LED is selected (green).
You may only modify the parameters for the channel that is currently selected (indicated
by the green LED). A green flashing LED indicates that the selected channel is in the
rest segment of its cycle. If the light is green and flashing when you begin to modify
intensity, pulse rate or pulse width, current is ramped up to treatment level for that
channel so those parameters may be modified.
9. Press START.
When you press start, the treatment timer begins counting down. If you fail to set the
intensity before pressing START, the intensity display will begin flashing, and you will
be unable to start the treatment until you set the intensity. For Reciprocal and Co-
contraction treatments, you must set the intensity for each channel separately.
SAVE DEFAULTS. If the treatment you have just set up is the most common Biphasic
or Russian treatment setup you use, you can save the treatment parameters as new
defaults for your own machine. After setting up the treatment, simply press and hold the
START key for two seconds. At the end of two seconds, you will hear a beep indicating
the treatment parameters have been saved. The next time you select this modality, these
parameters are selected automatically.
10. MODIFY settings.
While the treatment is in progress, you can modify the treatment parameters. You will
need to observe the channel indicator lights when modifying a treatment.
• When a channel’s light is green, the current treatment parameters for that channel are
displayed. Any changes you make to the parameters will affect the channel with the
green light only.
• When a channel’s light is yellow, the channel is still active, but its parameters are not
being displayed and it may not be modified until it is selected. You must first press
the toggle key to select the channel—its light will then become green and
modifications are allowed.
• When a light is solid (any color), this indicates the channel is in the CONTRACTION
segment of the cycle and current is being delivered to that channel. When a light is
flashing, this indicates the channel is in the REST segment of the cycle and current is
not being delivered at this time. If you select a channel for modification while its
light is flashing, the device will ramp the current up on that channel before allowing
you to make modifications. When the light changes from flashing green to solid
green, you will be able to modify the settings for the channel.
