20. EMC / Technical Description (cont.)
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 Symphony electric breast pump is used exceeds the
applicable RF compliance level above, the Symphony electric breast pump should be observed
to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the Symphony electric breast pump.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
