Electromagnetic
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® C 051
Thorax demands continued
function even in case of
interruptions of the energy
supply, it is recommended
to supply the ATMOS® C 051
Thorax from an uninterruptible
current supply or a battery.
