Compliance Electromagnetic environment – guidance
The Medical Bed uses RF energy only for its internal
function. Therefore, its RF emissions are very low and
Group 1
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
Class A
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.
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.
The power frequency magnetic field
should be at a characteristic level of a
typical commercial or hospital
environment.
