Electromagnetic envi-
ronment – guidance
Floors should be wood,
concrete or ceramic tile.
If floors are covered with
synthetic material, the re-
lative humidity should be
at least 30 %.
Mains power quality
should be that of a typi-
cal commercial or hospi-
tal environment.
Mains power quality
should be that of a typi-
cal commercial or hospi-
tal environment.
Mains power quality
should be that of a typi-
cal commercial or hos-
pital environment. If the
user of the IH20 requires
continued operation duri-
ng power mains interrup-
tions, it is recommended
that the IH20 be powered
from an uninterruptible
power supply or a battery.
