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