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

100 12 12 23
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 refl ection from structures, objects and people.
