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.

T T
Mains power quality should be that of a typical
commercial or hospital environment. If the user of the
(60% dip in U )for medical bed requires continued operation during power
T T
mains interruptions, it is recommended that the medical
bed be powered from an un-interruptible power supply
(30% dip in U ) for

or a battery.
U is the a. c. mains voltage prior to application of the

test level.
Power frequency magnetic fields should be at levels
characteristic of a typical location in a typical commercial
or hospital environment.
