Beurer BM 54 Gebrauchsanweisung Seite 130

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 survey should be considered.
If the measured field strength in the location in which the Blood pressure monitor (BM 54) is used exceeds the applicable RF
compliance level above, the Blood pressure monitor (BM 54) should be observed to verify normal operation. If abnormal perfor-
mance is observed, additional measures may be necessary, such as reorienting or relocating the Blood pressure monitor (BM 54).
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 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 sepa-
ration distance in metres (m).
Field strengths from fixed RF transmitters, as determined by an electroma-
gnetic site surveya should be less than the compliance level in each frequen-
cy rangeb. Interference may occur in the vicinity of equipment marked with
the following symbol:
