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 typi­
cal commercial or hospital environment. If the
user of the BM 44 requires continued operation
during power mains interruptions, it is recom­
mended that the BM 44 be powered from an
uninterruptible power supply or a battery.
Power frequency magnetic fields should be at
levels characteristic of a typical location in a
typical commercial or hospital environment.
