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
or hospital environment.
Mains power quality should be
that of a typical commercial
or hospital environment.
Mains power quality should be
that of a typical commercial or
hospital environment. If the user
of the [ME EQUIPMENT or ME
SYSTEM] requires continued
operation during power mains
interruptions, it is recommended
that the [ME EQUIPMENT or ME
SYSTEM] be powered from an
uninterrupted power supply or a
battery.
Power frequency magnetic
fields should be at levels
characteristic of a typical
location in a typical hospital or
home environment.
