13) Do not use the stimulator in the vicinity of shortwave or
microwave therapy equipment, since this may affect the
output power of the stimulator.
14) Never use it near the cardiac area. Stimulation
electrodes should never be placed anywhere
on the front of the thorax (marked by ribs and
breastbone), but above all not on the two large
pectoral muscles. There it can increase the risk of
ventricular fibrillation and lead to cardiac arrest.
15) Never use it on the eye, head and face area.
16) Never use it near the genitals.
17) Never use it on the areas of the skin which lack normal
sensation.
18) Keep electrodes separated during treatment. It could re sult
in improper stimulation or skin burns if electrodes are in
contact with each other.
19) Keep the stimulator out of reach of children.
20) Consult your doctor if you are in any doubt whatsoever.
21) Discontinue it and do not increase the intensity level if you
feel discomfort during use.

Precautions
1)
TENS is not effective for pain of central origin including
headache.
2)
TENS is not a substitute for pain medications and other pain
management therapies.
3)
TENS is a symptomatic treatment and, as such, suppresses
the sensation of pain that would otherwise serve as a
protective mechanism.
4)
Effectiveness is highly dependent upon patient selection by
a practitioner qualified in the management of pain patients.
