Portable and mobile RF
communications
equipment should be used no
closer to any part of the medi
pcs, including cables, than
the recommended separation
distance calculated from the
equation applicable to the
frequency of the transmitter.
Recommended separation
distance
E = [6/d] √P
d = [6/E] √P
where P is the maximum
output power rating of the
transmitter in watts (W)
according to the transmitter
manufacturer, d is the
recommended separation
distance in meters (m), and
E is the field strength in V/m.
Field strengths from fixed RF
transmitters, as determined
by an electromagnetic
site survey, should be less
than the compliance level
in each frequency range.
Interference may occur in the
vicinity of equipment marked
with the following symbol:
Guidance and Manufacturer’s Declaration – Electromagnetic Immunity
NOTE: These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects and people.
The medi pcs is intended for use in the electromagnetic environment specified below. The
customer or the user of the medi pcs should assure that it is used in such an environment.
