Guidance and manufacturer's declaration – electromagnetic emissions
Compliance
The Model 775 warming unit 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.
The Model 775 warming unit 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.
