Electromagnetic
environment—guidance
Floors should be wood,
concrete or ceramic tile. If
floors are covered with
synthetic material, 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.
Mains power quality should
be that of a typical
commercial or hospital
environment.
If the user of the S8 device
requires continued operation
during power mains
interruptions, it is
recommended that the S8
device be powered from an
uninterruptible power
source.
Power frequency magnetic
fields should be at levels
characteristic of a typical
location in a typical
commercial or hospital
environment.
