Guidance and manufacture's declaration – electromagnetic immunity
The BM 55 is intended for use in the electromagnetic environment specifi ed below. The customer or the user of the BM 55 should assure that it is
used in such an environment.

Electromagnetic environment – guidance
Floors should be wood, concrete or ceramic tile. If
fl oors 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 55
requires continued operation during power mains inter-
ruptions, it is recommended that the BM 55 be powered
from an uninterruptible power supply or a battery.
Power frequency magnetic fi elds should be at levels
characteristic of a typical location in a typical commer-
cial or hospital environment.
