Guidance and manufacture’s declaration – electromagnetic immunity
The BM 55 is intended for use in the electromagnetic environment specified below. The customer or the user of the BM 55 should assure that it is
used in such an 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 fields should be at levels
characteristic of a typical location in a typical commer-
cial or hospital environment.
NOTE: U
