Recommended separation distances between portable and
mobile RF communications equipment and the breast pump
This 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.
