Beurer BC 30 - Manual (Page 79)

Table 3
Guidance and manufacturer’s declaration – electromagnetic immunity
The BC 30 is intended for use in the electromagnetic environment specified below. The customer or the user of the BC 30 should assure that
it is used in such an environment.

Portable and mobile RF communications equipment should be used no closer to any part
of the BC 30, including cables, than the recommended separation distance calculated
from the equation applicable to the frequency of the transmitter.
Recommended separation distance:
d = 1.2
80 MHz to 800 MHz
d = 2.3 800 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).
Field strengths from fixed RF transmitters, as determined by an electromagnetic site
survey, a should be less than the compliance level in each frequency range. b
Interference may occur in the vicinity of equipment marked with the following symbol:
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 structu-
res, 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 envi-
ronment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location
in which the BC 30 is used exceeds the applicable RF compliance level above, the deivce should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the BC 30.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
