- guidelines
Floors should be made of wood
or cement, or covered with ce-
ramic tiles� If the floor is covered
by synthetic material, then the
relative humidity must be at
least 30%�
The quality of the supply voltage
should correspond to a typical
commercial or hospital environ-
ment�
The quality of the supply voltage
should correspond to a typical
commercial or hospital environ-
ment� If the operator of the de-
vice needs the unit to continue
working even if the mains power
supply is interrupted, we rec-
ommend powering the device
from an uninterruptible power
supply (UPS) or from a battery�
The magnetic fields at mains
frequency should be within the
range of typical values encoun-
tered in a commercial or hospi-
tal environment�
