The CEFAR REHAB X2 Electrotherapy System is intended for use in the electromagnetic environment deified below. The customer
or the user of the CEFAR REHAB X2 Electrotherapy System should assure that it is used in such an environment.
Immunity Test

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 REHAB X2 Electrotherapy System is used exceeds the applicable RF
compliance level above, the CEFAR REHAB X2 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 REHAB X2
Electrotherapy System .

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 REHAB X2 Electrotherapy System, including
cables, than the recommended separation distance
