Appendix B Regulatory Notices 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 changes the rating of some configurations to Class A. To determine which classification applies to your computer system, examine all FCC registration labels located on the 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 the Class B rating, your system is considered to be a Class B digital device. NOTE: Some Dell computer systems that are classified as Class B digital devices may include a built-in network interface controller (NIC). If your system contains a NIC, it is considered to be a Class A digital device only at the time that the NIC is being used. When the NIC is not being used, 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 Computer Corporation could void your authority to operate this equipment. A Notice About Shielded Cables: Use only shielded cables for connecting peripherals to any Dell device to reduce the possibility of interference with radio and television reception.

For parallel printers, a cable is available from Dell Computer Corporation. 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.
