Electromagnetic
environment – guidance
Portable and mobile RF communications equipment
should be used no closer to any part of the Sym-
phony electric breast pump, including cables, than
the recommended separation distance calculated
from the equation applicable to the frequency of the
transmitter.
Recommended separation distance
d = 0.35√P
d = 1.2√P
80 MHz to 800 MHz
d = 2.3√P
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 metres (m).
Field strengths from fixed RF transmitters, as determi-
ned by an electromagnetic site survey,
than the compliance level in each frequency range.
