Environment - Guidance
Floors should be wood,
concrete, or ceramics tile.
If floors are synthetic, 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.
Power frequency magnetic
fields 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 ATMOS S 201
Thorax requires continued
operation even in case of
interruptions of the energy
supply, it is recommended
that the ATMOS S 201
Thorax be powered by
an uninterruptible power
supply or a battery.
