Portable and mobile RF communications
equipment should be used no closer to any
part of the F Series Fetal & maternal
Monitor including cables, than the
recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.
Recommended separation distance
Pd 2.1 150 kHz to 80 MHz
Pd 2.1 80 MHz to 800 MHz
Pd 3.2 800 MHz to 2.5 GHz
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 meters (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.
b)
Interference may occur in the vicinity of
equipment marked with the following
