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