8.6 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.
Emissions test Compliance Electromagnetic environment - guidance
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.

Mains power quality should be that of a typical
commercial or hospital environment. If the
user of the medical 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.
