Electromagnetic environment - guidance
The medical used bed uses RF energy only for its internal function. Therefore, its RF emis-
sions are very lowand 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 purpose.

Electromagnetic environment - guidance
Floors should be wood, concrete or ceramic
tile. If floors are covered with synthetic mate-
rial, the relative humidity should be at least
30%.
Mains power quality should be that of a typi-
cal commercial or hospital environment.
Mains power quality should be that of a typi-
cal commercial or hospital environment.
Mains power quality should be that of a typi-
cal commercial or hospital environment. If the
user of the medizinisches Bett requires conti-
nued operation during power mains interrupti-
ons, it is recommended that the medizini-
sches Bett be powered from an uninter-
ruptible 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.
