Electromagnetic environment - guidance
The medizinisches Bett uses RF energy only for its internal function. Therefore, its RF
emissions are very low and are not likely to cause any interference in nearby electronic
equipment.
The medizinisches Bett is suitable for use in all establishments other than domestic and
those directly connected to the public-voltage power supply network that supplies buildings
used for domestic purposes.

Electromagnetic environment – guidance
Floors should be wood, concrete or ceramic tile.
If fl oors 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 medizinisches Bett requires continued
operation during power mains interruptions, it is
recommended that the medizinisches Bett be
powered from an uninterruptible power supply
or a battery.
Power frequency magnetic fi elds should be at
levels characteristic of a typical location in a
typical commercial or hospital environment.
