Guidance and manufacturer's declaration - electromagnetic immunity
The RadiForce series is intended for use in the electromagnetic environment specified below. The customer or the user
of the RadiForce series should assure that it is used in such an environment.
Immunity test
IEC60601 test level Compliance level
Conducted RF
3Vrms
EN61000-4-6
150kHz to 80MHz
Radiated RF
3V/m
80MHz to 2.5GHz
EN61000-4-3
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 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.

Electromagnetic environment - guidance
3V
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
3V/m
from the equation applicable to the frequency of
the transmitter.
Recommended Separation distance
d = 1.2 √ P
d = 1.2 √ P, 80MHz to 800MHz
d = 2.3 √ P, 800MHz to 2.5GHz
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
should be less than the compliance level in each
frequency range
Interference may occur in the vicinity of equipment
marked with the following symbol.
