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.

Type B Applied Part complying with the specified
Applied requirements for protection against electrical shock
Part according to IEC60601-1.
Sound level 55 dB (A)
Degree of The control unit, external power supply, motors
protection and hand controls are protected according to IPx4,
IPx6 or IPx6w (depending on configuration). See
bed product label and label on each electric device
for correct IP class. The lowest IP-classification
decides the overall classification of the bed.
IPx4 - The system is protected against water
splashed from any direction.
IPx6 - The system is protected against water
projected from any direction (not high pressure).
IPx6w - The system is protected against high
pressurized water and steam projected from any
direction.
The bed has no isolator (main switch). If the bed needs to
be electrically disconnected, it has to be unplugged from the
mains socket.
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.
