Electromagnetic environment – guidance
RF emission
CISPR 11
Group 1
The Preva Dental X-ray System 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 emission
CISPR 11
Class B
The Preva Dental X-ray System 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.
