12) Stimulation should not take place while the user is
connected to high-frequency hospital equipment,
which may cause burn injuries on the skin under the
electrodes, as well as problems with the unit.
13) Do not use the unit in the vicinity of shortwave or
microwave therapy equipment since this may affect
the output power of the stimulator.
14) Never use the unit near the cardiac area. Stimulation
electrodes should never be placed anywhere on the
front of the thorax (marked by ribs and breastbone) or
the two large pectoral muscles due to the increased
risk of ventricular fibrillation which could lead to
cardiac arrest.
15) Never use on the eyes, head and face or genital areas.
16) Never use on skin areas lacking normal sensation.
17) Keep electrodes separated during treatment. Improper
stimulation or skin burns could result if electrodes are
in contact with each other.
18) Keep the stimulator out of reach of children.
19) Consult your doctor or supervisory medical
professional if you are in any doubt whatsoever.
20) Discontinue use if any discomfort is felt.
21) TENS must NOT be used before the 37th week of
pregnancy.
22) If you are pregnant, do NOT place the electrodes over
your abdomen.
2.2.3 Precautions
1) TENS is not effective for pain of central origin including
