B. EMC Guidance and Manufacturer's Declaration
Guidance and manufacturer’s declaration-electromagnetic emissions
The device is intended for use in the electromagnetic environment specified below. The
customer or the user of the device should assure that it is used in such an environment.
Emission test Compliance
Electromagnetic
environment-guidance
RF emissions CISPR 11 Group 1
The device 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 emissions CISPR 11 Class A
The product is suitable for use in all
establishments other than domestic
and those directly connected to a
low voltage power supply network
which supplies buildings used for
domestic purposes.
Guidance and manufacturer’s declaration-electromagnetic immunity
