7. 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
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.

Recommended separation distances between portable and
mobile RF communications equipment and the breast pump
This Swing electric breast pump is intended for use in an electromagnetic environment
in which radiated RF disturbances are controlled. The customer or the user of the
electric breast pump can help prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communications equipment
(transmitters) and the electric breast pump as recommended below, according to the
maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in metres (m) can be estimated using the equation applicable to
the frequency of the transmitter, where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter manufacturer.
Note 1 At 80 MHz and 800 MHz, the separation distance for 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.
WARNING: Portable RF communications equipment (including peripherals such as
antenna cables and external antennas) should be used no closer than 30 cm (12
inches) to any part of the breast pump including cables specified by the manufacturer.
Otherwise, degradation of the performance of this equipment could result.
