17. EMC PRECAUTIONS
Use special precautions regarding EMC according to the information
provided below.
Guidance and manufacturer’s declaration - electromagnetic emissions
The mamaTENS is intended for use in the electromagnetic environment specified below.
The customer or the user of the mamaTENS should assure that it is used in such an environment.
Emissions test
