Beurer BM 90 - Manual (Page 101)

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 BM90 is used
exceeds the applicable RF compliance level above, the BM90 should be observed to verify normal operation.
If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating
the BM90.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
