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.

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.
