Electromagnetic environment – guidance
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.
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 BM57 can conti-
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.
