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 either the Class B rating or the FCC logo ( ), 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 classifica- tion, 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. Using shielded cables ensures that you maintain the appropriate FCC radio frequency emissions compliance (for a Class A device) or FCC certification (for a Class B device) of this product. For parallel printers, a cable is available from Dell Computer Corporation.

Class A

This equipment generates, uses, and can radiate radio fre- quency energy and, if not installed and used in accordance with the manufacturer’s instruction manual, may cause harmful interference with radio communica- tions. 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 harmful interference when the equipment is operated in a commercial environment. Operation of this equipment in a residential area is likely to cause harmful interference, in which case you will be required to correct the interfer- ence at your own expense.

Class B

This equipment generates, uses, and can radiate radio fre- quency energy and, if not installed and used in accordance with the manufacturer’s instruction manual, may cause interference with radio and television recep- tion. 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 interfer- ence in a residential installation. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful inter- ference with 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 the receiving antenna.

•Relocate the computer with respect to the receiver.

•Move the computer away from the receiver.
