Electromagnetic environment
Portable and mobile RF communications
equipment should be used no closer to
any part of the EUS T Ultrasound
Scanner, 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,
less than the compliance level in each
frequency range.
