Recommended separation distances between portable and mobile RF communications

equipment and the Paradigm 522/722/522K/722K pump system

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

mobile RF communications equipment and the P

aradigm 522/722/522K/722K pump. The Paradigm

522/722/522K/722K pump is intended for use in an electromagnetic environment in which radiated

RF disturbances are controlled. Paradigm 522/722/522K/722K pump users can help prevent

electromagnetic interference by maintaining a minimum distance between portable and mobile RF

communications equipment (transmitters) and the Paradigm 522/722/522K/722K pump as

recommended below, according to the maximum output power of the communications equipment.

Separation distance according to the frequency of transmitter (m)

Rated maximum

output power of

transmitter (W)

80MHz to 800MHz

d = 0.35

800MHz to 6.0GHz

d = 0.70

0.01 0.035 0.07

0.1 0.11 0.11

1 0.35 0.7

10 1.1 2.2

100 3.5 7

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.
