Radio communications servicesinclude but are not limited to AM/FM commercial broadcast, television, cellularservices, radar, air-traffic control, pager, and Personal Communication Services (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 tofunction properly together in the electronic environment. While this computer systemhas been designed and determined to be compliant with regulatory agency limits forEMI, there is no guarantee that interference will not occur in a particular installation. Ifthis equipment does cause interference with radio communications services, whichcan be determined by turning the equipment off and on, you are encouraged to try tocorrect 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 receiverare on different branch circuits.If necessary, consult a Dell Technical Support representative or an experienced radio/television technician for additional suggestions.
