Electromagnetic immunity
The RadiForce series has been tested at the following compliance levels according to the testing requirements for
professional healthcare facility environments defined in IEC / EN60601-1-2.
Customers and users of the RadiForce series must ensure that the RadiForce series is used in the following
environments:
Immunity test

environments
Conducted 3 Vrms
disturbances induced 150 kHz - 80 MHz
by RF fields
IEC / EN61000-4-6
6 Vrms
ISM bands between
150 kHz and 80 MHz
Radiated RF fields 3 V/m
IEC / EN61000-4-3 80 MHz - 2.7 GHz
Note 1 U is the a.c. mains voltage prior to application of the test level.
T
Note 2 At 80 MHz and 800 MHz, the higher frequency range applies.
Note 3 Guidelines regarding conducted disturbances induced by RF fields or radiated RF fields may not apply in all
situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
Note 4 The ISM bands between 150 kHz and 80 MHz are 6.765 MHz to 6.795 MHz, 13.553 MHz to 13.567 MHz, 26.957
MHz to 27.283 MHz, and 40.66 MHz to 40.70 MHz.
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 RadiForce series is used exceeds the applicable
RF compliance level above, the RadiForce series should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating the RadiForce series.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Guidance
Portable and mobile RF communications
equipment should be used no closer to any
part of the RadiForce series, including cables,
than the recommended separation distance
calculated from the equation applicable to the
frequency of the transmitter.
Recommended separation distance
d = 1.2√P
d = 1.2√P, 80 MHz - 800 MHz
d = 2.3√P, 800 MHz - 2.7 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
