RF emissions CISPR 11
Group 1
The NeXus-4 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.
RF emissions CISPR 11
Class B
The NeXus-4 is suitable for use in all
establishments, including domestic
establishments and those directly
connected to the public low-voltage power
supply network
that supplies buildings used for domestic
purposes.
