10 Specifications and Theory of Operation
Electromagnetic environment guidance
Floors should be wood, concrete, or
ceramic tile. If floors are covered with
synthetic material, the relative humidity
should be at least 30%.
Mains power quality should be that of a
typical commercial and/or hospital
environment.

If display distortion or other abnormalities
occur, it may be necessary to position
the Anesthetic System further from
sources of power frequency magnetic
fields or to install magnetic shielding. The
power frequency magnetic field should
be immersed in the intended installation
location to assure that it is sufficiently
low.
