A7.4 Recommended Separation Distances

portable and mobile RF communications equipment and the
The F Series Fetal & maternal Monitor is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the F Series Fetal & maternal
Monitor can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the F Series Fetal & maternal
Monitor 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 affected by
absorption and reflection from structures, objects and people.
