Compliance Electromagnetic environment - guidance
Group 1 The BC 50 uses RF energy only for its internal function. Therefore, its RF emissions are
very low and are not likely to cause any interference in nearby electronic equipment.
Class B The BC 50 is suitable for use in all establishments, including domestic establishments
and those directly connected to the public low-voltage power supply network that

The power frequency magnetic fieeld should be
measured in the intended installation location to
assure that it is sufficiently low.
