Portable and mobile RF communications
equipment should be used no closer to any
part of the K Pump and K Pump cabling
than the recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.

Where P is the maximum output power
rating of the transmitter in watt (W)
according to the transmitter manufacturer
and d is the recommended separation
distance in meters (m).
Field strengths from fixed RF transmitters
as determined by an electromagnetic site
survey should be less that the compliance
level in each frequency range.
Interference may occur in the vicinity of
equipment marked with the following
symbol:
Note: These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects, and people.
a. Field strengths from fixed transmitters such as base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio, AM and FM broadcast, and TV broadcast
cannot be predicted theoretically with accuracy.
To assess the electromagnetic environment due to fixed RF transmitters, and electromagnetic
site survey should be considered. If the measured field strength in the location in which the
K Pump is used exceeds the applicable RF compliance level above, the K Pump should be
observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the Pump.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
