Guidance and manufacturer's declaration – electromagnetic immunity
The BM 75 is intended for use in the electromagnetic environment specifi ed below. The customer or the user of the BM 75 should assure that it is
used in such an environment.
Immunity test IEC 60601 test
level
Conducted RF
IEC 61000-4-6 3 V
rms
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 aff ected by absorption and refl ection from structures,
objects and people.
a Field strengths from fi xed 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 fi xed RF
transmitters, an electromagnetic site survey should be considered. If the measured fi eld strength in the location in which the BM 75 is used exceeds
the applicable RF compliance level above, the BM 75 should be observed to verify normal operation. If abnormal performance is observed, additio-
nal measures may be necessary, such as re-orienting or relocating the BM 75.
b
Over the frequency range 150 kHz to 80 MHz, fi eld 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 75, 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
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
transmitter manufacturer and d is the recommended separation distance in meters (m).
Field strengths from fi xed 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:
