Portable and mobile RF communications
equipment should be used no closer to any
part of the ultrasound unit, including cables,
than the recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.
Recommended separation distance

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

Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
a
survey, should be less than the compliance
level in each frequency range.
