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.

requires continu-
ed operation du-
ring power mains
interruptions, it
is recommended
that the Diag-
nostic station
ri-former ® be
powered from an
uninterruptible
power supply or
a battery.
Power frequency
magnetic fields
should be at level
characteristic of
a typical loca-
tion in a typical
commercial or
hospital environ-
ment
