Guidance and manufacture’s declaration – electromagnetic immunity
The SR BM 1 is intended for use in the electromagnetic environment specified below. The customer or the user of SR BM 1 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%.
Electrical fast

IEC 61000-4-4
± 2 kV for power supply
lines
± 1 kV for input/output

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. The SR BM 1 can con-
tinue the operation during power mains interruptions
due to the usage of battery.
Power frequency

3 A/m
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.
