18 . Electro Magnetic Compliance (EMC)
The Medical Bed is intended for use in the electromagnetic environment specified below. The user of the Medical
bed should assure that it is used in such an environment.
Emissions test Compliance Electromagnetic environment – guidance
RF emissions
CISPR 11
Group 1
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.
RF emissions
CISPR 11
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.

Mains power quality should be that of a
typical commercial or hospital
environment. If the user of the
Medical bed Alegio requires
continued operation during power
mains interruptions, it is recommended
that the Medical Bed Alegio be
powered from an uninterruptible
power
supply or a battery.
