RF emissions CISPR 11 Group 1 The BM49 blood pressure monitor uses RF energy only for its internal function.
Therefore, its RF emissions are very low and are not likely to cause any interfe-
rence in nearby electronic equipment.
RF emission CISPR 11 Class B The BM49 blood pressure monitor is suitable for use in all establishments, inclu-
ding domestic establishments and those directly connected to the public low-vol-
tage power supply network that supplies buildings used for domestic purposes.

Portable and mobile RF communications equipment should be used no clo-
ser to any part of the BM49 blood pressure monitor, including cables, than
the recommended separation distance calculated from the equation appli-
cable 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 sepa-
ration distance in metres (m).
Field strengths from fixed RF transmitters, as determined by an electroma-
gnetic site survey, a should be less than the compliance level in each fre-
quency range. b
