Electromagnetic environment – guidance
The BS901 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.
The BS901 is intended for use in the electromagnetic environment specified
below. The customer or the user of the BS901 should assure that it is used in
such an environment .
