displayed while intensity is being set or changed. See page 21 for a complete explanation
of the conductance bar graph.
Before selecting the intensity setting for an individual patient, see “Electrotherapy Usage
Cautions” in this manual 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.
6. Choose
TARGET, SWEEP, or STATIC (for interferential only).
TARGET. Press the toggle key to select this option if it is not already selected. The
patented Target feature allows you to pinpoint the treatment site to deliver the full
interferential current where it is needed. NOTE: You must set the intensity before using
the Target Pad so the patient will be able to tell you when the treatment site is found.
Also remember, an injured area will often be more sensitive to the current delivered.
Therefore, an intensity setting that is comfortable to the patient at first may feel
uncomfortable when the treatment site is found using the Target pad. If necessary,
reduce the intensity to the patient’s comfort level.
SWEEP. Press the toggle key one or more times to select this option. This option uses
Dynatronics’ patented Target feature to automatically move the point of interference in a
somewhat spiral fashion covering 75 to 80 percent of the area within the electrodes. This
allows you to bathe a more general area with the interferential current while retaining the
full interferential beat.
STATIC. This option is applied when neither Target nor Sweep are selected. Press the
toggle key one or more times to unselect those options (the LEDs will both be off). The
treatment becomes a STATIC treatment. In other words, it simply allows the two
currents to take a path of least resistance and intersect at a natural point within the
electrodes.
7. Press
START.
When you press start, the treatment timer begins counting down and the treatment
proceeds. 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.
SAVE DEFAULTS. If the treatment you have just set up is a common 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 that modality, these parameters are selected
automatically.
8. MODIFY settings.
While the treatment is in progress, you can modify any of the treatment parameters, if
desired. Note: If you change the treatment time during a consecutive High/Low treatment,
the treatment will revert to alternating High/Low.
