Guidance and manufacturer's declaration – electromagnetic immunity
BM 60 is intended for use in the electromagnetic environment specified below. The customer or the user of BM 60 should assure that it is used
in such an environment.
Immunity test IEC 60601 test
level
Conducted RF 3 V
rms
IEC 61000-4-6 150 kHz to 80 MHz
Radiated RF 3 V/m
IEC 61000-4-3 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 strength from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM
and FM radios 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 BM 60 is
used exceeds the applicable RF compliance level above, BM 60 should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating BM 60.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
Compliance Electromagnetic environment – guidance
level
Portable and mobile RF communications equipment should be used no closer to any part
of BM 60, including cables, than the recommended separation distance calculated from
the equation applicable to the frequency of the transmitter.
Recommended separation distance:
d = [ 3.5 / V1 ]
3 V
d = [ 3.5 / E1 ]
d = [ 7 / E1 ]
3 V/m
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 metres (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:
80 MHz to 800 MHz
800 MHz to 2.5 GHz
