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 com-
mercial or hospital environment.
Mains power quality should be that of a typical com-
mercial or hospital environment.
Mains power quality should be that of a typical com-
mercial or hospital environment. If the user of the BM 16
requires continued operation during power mains inter-
ruptions, it is recommended that the BM 16 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 commer-
cial or hospital environment.
