Electromagnetic environment – guidance
Floors should be wood, concrete or cera-
mic tile. If floors are covered with synthetic
material, the relative humidity should be at
least 30 %.
Mains power quality should be that of a typi-
cal commercial or hospital environment.
Mains power quality should be that of a typi-
cal commercial or hospital environment.
Mains power quality should be that of a typi-
cal commercial or hospital environment. If
the user of BM47 requires continued ope-
ration during power mains interruptions, it
is recommended that BM47 is 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 envi-
ronment.
