The CEFAR PERISTIM PRO Electrotherapy System is intended for use in the electromagnetic environment deified below. The
customer or the user of the CEFAR PERISTIM PRO Electrotherapy System should assure that it is used in such an environment.
Immunity Test
Conducted RF 3 Vrms
IEC 61000-4-6 150 kHz to 80 MHz
Radiated RF 3 V/m
IEC 61000-4-3 80 MHz to 2,5 GHz
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection
from structures, objects and people.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios,
amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess
the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If
the measured field strength in the location in which the CEFAR PERISTIM PRO Electrotherapy System is used exceeds the
applicable RF compliance level above, the CEFAR PERISTIM PRO Electrotherapy System should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the
CEFAR PERISTIM PRO Electrotherapy System .
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V 1 ] V/m.

Electromagnetic Environment - Guidance
Portable and mobile RF communications
equipment should be used no closer to any part of
the CEFAR PERISTIM PRO Electrotherapy System,
including cables, than the recommended separation
distance calculated from the equation applicable to
the frequency of the transmitter.
