Power frequency magnetic
fields should be at levels
characteristic of a typical
location in a typical commercial
or hospital environment.
Electromagnetic environment
-guidance
Portable and mobile RF
communications equipment
should be used no closer to any
part of the device, including
cables, than the recommended
separation distance calculated
from 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 and d is the
recommended separation distance
in metres (m).
Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey, a
should be less than the compliance
level in each frequency
range.
Interference may occur in the
vicinity of equipment marked with
