9.2.2 Electromagnetic compatibility, immunity
Guidelines and manufacturer's declaration -
Electromagnetic compatibility, immunity to interference
The Kröber O2 is intended for operation in an environment as specified below. The operator of the
Kröber O2 must ensure that it is operated in such an environment.
