B.1 Electromagnetic compatibility
Definition
Electromagnetic compatibility is the ability of equipment or systems to be used in their inten-
ded environment within designed efficiency levels without causing or receiving degradation
due to unintentional electromagnetic interference.
The D4xx also satisfies the requirements of the EMC regulations of the internal European
market.
Information on interference immunity and EMC conformance are provided in the following.
