Electromagnetic
Environment – Guidance
Floors should be wood, concrete
or ceramic tile. If floors are
covered with synthetic material,
the relative air humidity should
be at least 30%.
Mains power should be that of
a typical commercial or hospital
environment.
Mains power should be that of
a typical commercial or hospital
environment.
Mains power should be that of
a typical commercial or hospital
environment. If the user of the
equipment requires continued
operation during power mains
interruptions, it is recommended
that the equipment be powered
from an uninterruptible power
supply or a battery.
Power frequency magnetic
fields should be at levels
characteristics of a typical
location in a typical commercial
or hospital environment.
