For ME EQUIPMENT and ME SYSTEMS that are not LIFE-SUPPORTING
Guidance and manufacture's declaration – electromagnetic immunity
The BC 28 is intended for use in the electromagnetic environment specified below. The customer or the user of the BC 28 should
assure that it is used in such an environment.
Immunity test IEC 60601
test level
3 V/m
Radiated RF
80 MHz to
IEC 61000-4-3
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, ama-
teur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electroma-
gnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength
in the location in which the BC 28 is used exceeds the applicable RF compliance level above, the BC 28 should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the
BC 28.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
b
Compliance Electromagnetic environment – guidance
level
Portable and mobile RF communications equipment should be used no closer to any part
of the BC 28, including cables, than the recommended separation distance calculated
from the equation applicable to the frequency of the transmitter.
Recommended separation distance:
d = 1.2
3 V/m
d = 2.3
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.
