Manufacturer’s guide and statement – electromagnetic emissions
The device is intended to operating in the electromagnetic environment indicated below. The device customer or user must
guarantee that it is used in this environment.
Emission test

Electromagnetic environment - guide
RF emissions
CISPR 11
Group 1
The device only uses RF energy for its internal operations.
Consequently, its RF emissions are very low and most likely do not cause
any interferences with nearby electronic equipment.
RF emissions
CISPR 11
Class B
The device is suited for use in all environments, including home ones
and those directly connected to a low voltage public mains that powers
buildings used for residential purposes.
