FCC Notices (U.S. Only)
Most Dell computer systems are classified by the Federal Communications
Commission (FCC) as Class B digital devices. However, the inclusion of certain
options can change the rating of some configurations to Class A. To determine which

located on the bottom or back panel of your computer, on card-mounting brackets,
and on the cards themselves. If any one of the labels carries a Class A rating, your
entire system is considered to be a Class A digital device. If all labels carry an FCC
Class B rating as distinguished by either an FCC ID number or the FCC logo, ( ),
your system is considered to be a Class B digital device.
