Sanitas SBC 53 Mode D'emploi page 94

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 re-
flection 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 con-
sidered. If the measured field strength in the location in which the Blood pressure monitor (SBC 53) is used exceeds the
applicable RF compliance level above, the Blood pressure monitor (SBC 53) should be observed to verify normal opera-
tion. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the
Blood pressure monitor (SBC 53).
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 separation distance in metres (m).
Field strengths from fixed RF transmitters, as determined by an
electromagnetic site surveya should be less than the compliance
level in each frequency rangeb. Interference may occur in the vicinity
of equipment marked with the following symbol:
