Guidance and manufacture's declaration – electromagnetic immunity
The BC80 blood pressure monitor is intended for use in the electromagnetic environment specified below. The customer or the user of the BC80
blood pressure monitor 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 a ected 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 BC80 blood
pressure monitor is used exceeds the applicable RF compliance level above, the BC80 blood pressure monitor should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the BC80 blood pres-
sure monitor.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distances between portable and mobile RF communications equipment and the EQUIPMENT or SYSTEM – for
Compliance Electromagnetic environment – guidance
level
Portable and mobile RF communications equipment should be used no closer to any part of the BC80
blood pressure monitor, including cables, than the recommended separation distance calculated from
the equation applicable to the frequency of the transmitter.
Recommended separation distance:
d =
3 V
rms
d = 80 MHz to 800 MHz
d = 800 MHz to 2.5 GHz
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,
less than the compliance level in each frequency range.
