electrical stimulators are intended for use in the electromagnetic environment specified below.
The customer or the user of these electrical stimulators should assure that it is used in such
environment
.

Radiated RF
lEC 61000-4-3
Not applicable
3 V/m
80 MHz to 2.5 GHz
3 V/m
Portable and mobile RF
Communications equipment should be used no closer to any
part of the device, including cables, than the recommended
separation distance calculated from the equation applicable to
the frequency of the transmitter.
Recommended separation distance
d = 1.2 √

80 MHz to 800 MHz
d = 2.3 √
P
800 MHz to 2.5 GHz
Where P is the maximum output power rating of the transmitter
in watts (W) according to the. Transmitter manufacturer and d is
the recommended separation distance in meters (m).
Field strengths from fixed RF transmitters, as determined
by an electromagnetic site survey,
a
should be less than the
compliance level in each frequency range.
b
Interference may occur in the vicinity of
equipment marked with the following symbol:
TABLE

:
NOTE I At 80 MHz ends 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 device is used exceeds the applicable RF compliance level above, should
be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the device.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
