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, ac-
cording to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommened separation dis-
tance (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.
