Guidance and manufacture's declaration – electromagnetic immunity
The BM49 blood pressure monitor is intended for use in the electromagnetic environment specified below. The customer or the user of the BM49 blood pressure monitor
should assure that it is used in such an environment.

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 sur-
vey should be considered. If the measured field strength in the location in which the BM49 blood pressure monitor is used exceeds the applicable RF compliance level
above, the BM49 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 BM49 blood pressure monitor.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Electromagnetic environment – guidance
Portable and mobile RF communications equipment should be used no closer to any part of the BM49 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 =
d = 80 MHz to 800 MHz
d = 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 metres (m).
