Recommended separation distances between portable and mobile RF communications

equipment and the Paradigm 554/754 pump system

This section provides information on the recommended separation distance between portable and

mobile RF communications equipment and the Paradigm 554/754 pump. The Paradigm 554/754 pump

is intended for use in an electromagnetic environment in which radiated RF disturbances are

controlled. Paradigm 554/754 pump users can help prevent electromagnetic interference by

maintaining a minimum distance between portable and mobile RF communications equipment

(transmitters) and the Paradigm 554/754 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 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: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.

NOTE: These guidelines may not apply in all situations. Electromagnetic propagation is affected by

absorption and reflection from structures, objects and people.
