Recommended Separation Distances between Portable
and Mobile RF Communications Equipment and the Empi
Continuum
The Empi Continuum is intended for use in an electromagnetic environment
in which radiated RF disturbances are controlled. The customer or the user
of the Empi Continuum can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Empi Continuum 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.
