EMC guidelines
Floors should be wood, concrete
or ceramic tile. If floors are
covered with synthetic material,
the relative humidity should be
at least 30%
Grid power quality should be
that of a typical commercial or
hospital environment

that of a typical commercial or
hospital environment.

The magnetic field power
frequency should be at levels
characteristic for a commercial
or hospital environment.
