-guidelines
Floors should be
made of wood
or concrete or be
covered with
ceramic tiles. If
the floor is
covered with a
synthetic materi-
al, the relative air
humidity must be
at least 30%.
The quality of the
supply voltage
should corres-
pond to that of a
typical business
or hospital
environment.

ring power mains
interruptions, it
is recommended
that the Diag-
nostic station

be
powered from an
uninterruptible
power supply or
a battery.
Power frequency
