Electromagnetic environment - guidance
The medical bed 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 medical bed is suitable for use in all establishments including domestic
establishments and those directly connected to the public low-voltage power
supply network that supplies buildings used for domestic purposes.

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.
(>95% dip in U )
Mains power quality should be that of a typical
T T
commercial or hospital environment. If the
user of the medical bed requires continued
(60% dip in U

operation during power mains interruptions, it is
recommended that the medical bed be powered
from an un-interruptible power supply or a
(30% dip in U )
T T
battery.
U is the a. c. mains voltage prior to application

T T
of the test level.
Power frequency magnetic fields should be at
levels characteristic of a typical location in a
typical commercial or hospital environment.
Portable and mobile RF communications
equipment should be used no closer to any part
of the medical bed including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency
of the transmitter.
