Appendix 119
FCC Notices (U.S. Only)
Most Dell computer systems are classified by the Federal Communications Commission (FCC) as
Class B digital devices. To determine which classification applies to your computer system, 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 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.
Once you have determined your system’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.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions:
This device may not cause harmful interference.
This device must accept any interference received, including interference that may cause undesired
operation.
Class A
This equipment has been tested and found to comply with the limits for a Class A digital device
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against

This equipment has been tested and found to comply with the limits for a Class B digital device
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the manufacturer’s instruction
manual, may cause interference with radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause harmful interference
to radio or television reception, which can be determined by turning the equipment off and on, you are
encouraged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/television technician for help.
