Guidance and manufacture’s declaration – electromagnetic immunity
The BM57 is intended for use in the electromagnetic environment specified below. The customer or the user of BM57 should assure that it is used in
such an environment.
Immunity test
IEC 60601 test level Compliance level
Electromagnetic environment – guidance
Electrostatic discharge
(ESD) IEC 61000-4-2
± 6 kV contact
± 8 kV air
± 6 kV contact
± 8 kV air
Floors should be wood, concrete or ceramic tile. If floor
are covered with synthetic material, the relative humi
-
dity should be at least 30%.

Mains power quality should be that of a typical com-
mercial or hospital environment.

nue the operation during power mains interruptions due
to the usage of battery.

Mains power quality should be that of a typical com-
mercial or hospital environment.
NOTE:
U
T
is the a.c. mains voltage prior to application of the test level.
