9.5 Electromagnetic compliance (EMC)
Guidance and manufacturer´s declaration – electromagnetic emission
The medical bed is intended for use in the electromagnetic environment specified below. The customer or the user of the bed should assure
that it is used in such an environment.

RF emissions
CISPR 11(partly)
Group I
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.

Class B
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.

bed requires continued operation during power mains
interruptions, it is recommended that the medical bed
be powered from an un-interruptible power supply or
a battery.
