19. 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 refl ection from structures, objects and people.
a
Field strengths from fi xed 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 fi xed RF transmitters, an electromagnetic site survey should be considered. If the measured fi eld
strength in the location in which the Symphony electric breastpump is used exceeds the applicable
RF compliance level above, the Symphony electric breastpump 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 breastpump.
b
Over the frequency range 150 kHz to 80 MHz, fi eld strengths should be less than 10 V/m.
