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 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 field
should be at levels characteristic of a
typical location in a typical
commercial or hospital environment.
