EMISSIONS T EST COMPLIANCE ELECTROMAGNETIC ENVIRONMENT - GUIDANCE
RF emissions
CISPR 11
Group 1 The device 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 device is suitable for use in all establishments, including domestic
establishments and those directly connected to the public low-voltage
power supply network.
