12. TECHNICAL DATA
CEFAR PRIMO PRO is a nerve stimulator (TENS) with two independent channels. It has seven preset
programs and three custom programs. Programs and amplitude can be individually set for each chan-
nel.
Treatment with electrical stimulation requires the stimulation current to penetrate the resistance of
the skin and the electrode, about 1500 ohms. CEFAR PRIMO PRO 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 cur-
rent changes 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.
