Recommended separation distances between portable and mobile RF
communications equipment and the K Pump.
The K Pump is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer r user of the K Pump can help prevent
electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the K 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: These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflections from structures, objects, and people.
