Guidance and manufacturer's declaration – electromagnetic immunity
This breast pump is intended for use in the electromagnetic environment
specified below. The customer or the user of the breast pump should ensure
that it is used in such an environment .

Interference may occur in the
vicinity of equipment marked

with the following symbol:
80 MHz – 2.7 GH z
80 % AM at 1 kHz
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 breast pump is used exceeds the applicable RF
compliance level above, the 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 breast pump.
b.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less
than 10 V/m.
WARNING: Portable RF communications equipment (including
peripherals such as antenna cables and external antennas) should be
used no closer than 12 inches (30cm) to any part of the breast pump
including cables specified by the manufacturer. Otherwise, degradation
of the performance of this equipment could result.
