Recommended separation distances between portable and mobile RF
communications equipment and the Symphony electric breast pump
The Symphony 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.

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.
