electromagnetic environ-
ment - guidance
Floors should be wood, con-
crete or ceramic tile. If floor
are covered with synthetic
material, the relative humidity
should be at least 30%.
Mains power quality should
be that of a typical commer-
cial or hospital environment.
Mains power quality should
be that of a typical commer-
cial or hospital environment.
Mains power quality should
be that of a typical commer-
cial or hospital environment.
If the user of the BM90
requires continued operation
during power mains inter-
ruptions, it is recommended
that the BM90 be powered
from an uninterruptible power
supply or a battery.
Power frequency magnetic
fields should be at levels
characteristic of a typical lo-
cation in a typical commercial
or hospital environment.
