Electromagnetic interferences
The
FRED easy®
is intended to be used in the electromagnetic environments listed
in the following tables. The owner or user of the
FRED easy®
has to ensure that the
device is operated in an adequate environment.

Electromagnetic environment - explanations
HF emissions
CISPR 11
Group 1
FRED easy®
only uses HF energy for internal functions. Therefore,
HF emissions are very low and interferences with electronic devices
nearby are unlikely.

Class B
FRED easy®
is suitable for use in all establishments, including do-
mestic establishments and those directly connected to the public
low-voltage power supply network that supplies buildings used for
domestic purposes.
