The Federal Communications Commission (FCC) has rules to protect
wireless communications from interference. The FCC places digital
electronics into two classes. These classes are known as Class A (for use
in industrial-commercial locations only) or Class B (for use in residential
or commercial locations). Depending on where it is operated, this product
could be subject to restrictions in the FCC rules. (In Canada, the
Department of Communications (DOC), of Industry Canada, regulates
wireless interference in much the same way.)
Digital electronics emit weak signals during normal operation that can
affect radio, television, or other wireless products. By examining the
product you purchased, you can determine the FCC Class and therefore
which of the two FCC/DOC Warnings apply in the following sections.
(Some products may not be labeled at all for FCC; if so, the reader should
then assume these are Class A devices.)
FCC Class A products only display a simple warning statement of one
paragraph in length regarding interference and undesired operation. Most
of our products are FCC Class A. The FCC rules have restrictions regarding
the locations where FCC Class A products can be operated.
FCC Class B products display either a FCC ID code, starting with the
letters EXN, or the FCC Class B compliance mark that appears as shown
below.
