12. TECHNICAL DATA

CEFAR BASIC is a nerve stimulator (TENS) with two non-independent channels and three preset pro-
grams.
Treatment with electrical stimulation requires the stimulation current to penetrate the resistance of
the skin and the electrode, about 1500 ohms. CEFAR BASIC can penetrate this resistance and maintain
a current of up to 60 mA. With a change in load from 100 to 1500 ohms, the stimulation current chan-
ges less than 10% from the set value.
The stimulator operates on either two non-rechargeable 1.5 V AA batteries or two rechargeable 1.2 V
AA batteries, recharged in a separate charger.
