Recommended Separation Distance; Distancia De Separación Recomendada; Distance Recommandée - Medela Invia Liberty Manual De Uso

Electromagnetic Compatibility (EMC, IEC 60601-1-2:2007, Table 6)
Recommended separation distance between portable
and mobile RF communications equipment and the
Invia Liberty Pump
The Invia Liberty Pump is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the Invia Liberty Pump
can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the Invia Liberty
Pump as recommended below, according to the maximum output power of the communi-
cations equipment.

For transmitters rated at a maximum output power not listed above, the recommened separation
distance (d) in meters (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.
