Electromagnetic Compatibility (EMC, IEC 60601-1-2:2007, Table 6)
Recommended separation distances between portable and mobile RF
communications equipment and the electric breast pump Symphony
The Symphony 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 Symphony
electric breast pump can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the
Symphony 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.
