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 electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equip-
ment (transmitters) and the 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 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 aected by absorption and reection from structures,
objects and people.
