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 this system requires
continued operation during
power mains interruptions, it is
recommended for this system
to be powered from an
uninterruptible power supply.
Power frequency magnetic
fields should be at levels
characteristic of a typical
location in a typical commercial
or hospital environment.
