Recommended separation distance between portable and mobile RF
communications equipment and the Electrical Stimulator
The Electrical Stimulator are intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The
customers or the users of these Electrical Stimulator can help prevent
electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the
Electrical 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:
At 80MHz and 800MHz, the separation distance for the higher pole
frequency range applies
Note:
These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures,
objects, and people.
Note:
EMC tests conducted including attached electrode cord
of 1.5 m length.
