Guidance and manufacturer's declaration – electromagnetic immunity
The BM 44 is intended for use in the electromagnetic environment specified below. The customer or the user of the BM 44 should assure that it is
used in such an environment.
IMMUNITY IEC 60601
test test level
Conducted RF 3 V
rms
IEC 61000­4­6 150 kHz to
80 MHz
Radiated RF 3 V/m
IEC 61000­4­3 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 BM 44 is
used exceeds the applicable RF compliance level above, the BM 44 should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re­orienting or relocating the BM 44.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Compliance Electromagnetic environment – guidance
level
Portable and mobile RF communications equipment should be used no closer to any part of the BM
44, including cables, than the recommended separation distance calculated from the equation appli­
cable to the frequency of the transmitter.
Recommended separation distance:
d = 1,2
3 V
rms
d = 1,2 80 MHz to 800 MHz
3 V/m
d = 2,3 800 MHz to 2,5 GHz
Where P is the maximum output power rating of the transmitter in watts (W) according to the trans­
mitter manufacturer and d is the recommended separation distance in meters (m).
Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey,
be less than the compliance level in each frequency range.
Interference may occur in the vicinity of equipment marked with the following symbol:
