Regulatory Notices C-1A P P E N D I X CRegulatory NoticesElectromagnetic Interference (EMI) is any signal or emission, radiated in free space or conductedalong power or signal leads, that endangers the functioning of a radio navigation or other safety ser-vice or seriously degrades, obstructs, or repeatedly interrupts a licensed radio communicationsservice. Radio communications services include but are not limited to AM/FM commercial broad-cast, television, cellular services, radar, air-traffic control, pager, and Personal CommunicationServices (PCS). These licensed services, along with unintentional radiators such as digital devices,including computer systems, contribute to the electromagnetic environment.Electromagnetic Compatibility (EMC) is the ability of items of electronic equipment to functionproperly together in the electronic environment. While this computer system has been designed anddetermined to be compliant with regulatory agency limits for EMI, there is no guarantee that inter-ference will not occur in a particular installation. If this equipment does cause interference withradio communications services, which can be determined by turning the equipment off and on, youare 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.• Plug the computer into a different outlet so that the computer and the receiver are on differentbranch circuits.If necessary, consult a Technical Support representative of Dell Computer Corporation or an experi-enced radio/television technician for additional suggestions. You may find the FCC InterferenceHandbook, 1986, to be helpful. It is available from the U.S. Government Printing Office, Washing-ton, DC 20402, Stock No. 004-000-00450-7 or on the World Wide Web at http://www.fcc.gov/Bureaus/Compliance/WWW/tvibook.html.Dell computer systems are designed, tested, and classified for their intended electromagnetic envi-ronment. These electromagnetic environment classifications generally refer to the followingharmonized definitions:• Class A is typically for business or industrial environments.• Class B is typically for residential environments.Information Technology Equipment (ITE), including peripherals, expansion cards, printers, input/output (I/O) devices, monitors, and so on, that are integrated into or connected to the system shouldmatch the electromagnetic environment classification of the computer system.
