Guidance and Manufacturer's Declaration – Electromagnetic Immunity
The Bone Growth Stimulator is intended for use in the electromagnetic environment specified
below. The customer or the user of the Bone Growth Stimulator should assure that it is used in
such an environment.
Immunity IEC 60601
Test Test Level
Conducted RF 3 Vrms
IEC 61000-4-6 150 kHz to
80 MHz
Radiated RF 3V/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 Bone Growth Stimulator is used exceeds the applicable
RF compliance level above, the Bone Growth Stimulator should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the Bone Growth Stimulator.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
Compliance Electromagnetic Environment
Level
3V Portable and mobile RF communications
equipment should be used no closer to
any part of the Bone Growth Stimulator,
including cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of
3 V/m
the transmitter.
Recommended separation distance:

distance in meters (m).
