Guidance and manufacturer’s declaration – electromagnetic immunity
BM55 is intended for use in the electromagnetic environment specified below. The customer or the user of BM55 should assure that it is
used in such an environment.

Mains power quality should be that of a typi-
cal commercial or hospital environment. If
the user of BM55 requires continued ope-
ration during power mains interruptions, it
is recommended that BM55 is 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 commercial or hospital envi-
ronment.
