Beurer medical BM 47 Mode D'emploi page 104

Radiated RF 3 V/m 80
IEC 61000-4-3 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 affected by absorption and reflection from struc-
tures, 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
BM 47 is used exceeds the applicable RF compliance level above, the BM 47 should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or relocating the BM 47.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Portable and mobile RF communications equipment should be used no closer to any part
of the BM 47, including cables, than the recommended separation distance calculated from
the equation applicable to the frequency of the transmitter.
Recommended separation distance:
3 V/m
d 1 2 . P

d 2 3 . P

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 fixed 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
