Adjusting the Polarity and Sensitivity
Select Polarity:
The Polarity Setting is found at the bottom/back of
unit. Negative (-) is similar to applying an ice pack,
positive (+) is like applying a heat pack. The default
setting is negative.
It is recommended that when selecting polarity, you begin with negative;
if pain worsens after 2 to 3 treatments, switch the polarity to positive and
re-treat the area.
Adjust Sensitivity Dial:
The Sensitivity Dial assists in accurate point
location. The DNS OTC locates areas of low
impedance by measuring changes in skin resistance,
which is influenced by moisture. Normal skin
should have dial pointing upwards to 3 (11 o’clock).
KEY TIP:
Once the sensitivity dial is “set” to a patient’s skin type, further
adjustment is rarely necessary. Circumstances where adjustments may
be required include, weather (ie. humidity), and individual’s hydration.
