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.
(>95 % dip in U ) Mains power quality should be that of a typical com-
T T
mercial or hospital environment. If the user of the BM 55
(60 % dip in U ) requires continued operation during power mains inter-
T T
ruptions, it is recommended that the BM 55 be powered
(30 % dip in U ) 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.
