If image distortion occurs, it
may be necessary to
position the Fujfilm Sonosite
ultrasound system further
from sources of power
frequency magnetic fields or
to install magnetic shielding.
The power frequency
magnetic field should be
measured in the Intended
installation location to assure
that it is sufficiently low.
Portable and mobile RF
communications equipment
should be used no closer to
any part of the Sonosite PX
ultrasound system including
cables, than the
recommended separation
distance calculated from the
equation applicable to the
frequency of the transmitter.
