Recommended separation distances between portable and mobile RF
communications equipment and the Bone Growth Stimulator
The Bone Growth Stimulator is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of the Bone Growth
Stimulator can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and
the Bone Growth Stimulator 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.
