Electromagnetic Environment
Floors should be wood, concrete or
ceramic tile. If floors are covered with
synthetic material, the relative humidity
should be at least 30%.

If image distortion occurs, it may be
necessary to position the 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.
