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

For transmitters rated at a maximum output power not listed above, the recommended separa-
tion distance d in meters (m) can be determined 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.
