Electromagnetic Environment - guidance
RF Emissions CISPR 11
Group 1
The eego amplifier 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 eego amplifier is suitable for use in all establishments,
including domestic and those directly connected to the
public low-voltage power supply network that supplies
buildings used for domestic purposes.
