Table 3
Guidance and manufacturer's declaration – electromagnetic immunity
The BC 32 is intended for use in the electromagnetic environment specifi ed below. The customer or the user of the BC 32 should assure that it is
used in such an environment.
Immunity test IEC 60601 test
level
Conducted RF 3 V 150 kHz
rms
IEC 61000-4-6 to 80 MHz
Radiated RF 3 V/m 80 MHz
IEC 61000-4-3 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
BC 32 is used exceeds the applicable RF compliance level above, the deivce should be observed to verify normal operation. If abnormal per-
formance is observed, additional measures may be necessary, such as reorienting or relocating the BC 32.
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 BC 32, including cables, than the recommended separation distance calculated from
the equation applicable to the frequency of the transmitter.
Recommended separation distance:
Not applicable
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 metres (m).
Field strengths from fi xed RF transmitters, as determined by an electromagnetic site
a
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
