FCC Notices (U.S. Only)
Most Dell computers are classified by the Federal Communications Commission (FCC) as
Class B digital devices. To determine which classification applies to your computer, examine all
FCC registration labels located on the bottom, side, 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 computer 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
computer is considered to be a Class B digital device.
Once you have determined your computer’s FCC classification, read the appropriate FCC
notice. Note that FCC regulations provide that changes or modifications not expressly approved
by Dell could void your authority to operate this equipment.
