108 Appendix
Regulatory Notices
Electromagnetic Interference (EMI) is any signal or emission, radiated in free space or
conducted along power or signal leads, that endangers the functioning of a radio navigation
or other safety service or seriously degrades, obstructs, or repeatedly interrupts a licensed
radio communications service. Radio communications services include but are not limited to
AM/FM commercial broadcast, television, cellular services, radar, air-traffic control, pager,
and Personal Communication Services (PCS). These licensed services, along with
unintentional radiators such as digital devices, including computers, contribute to the
electromagnetic environment.
Electromagnetic Compatibility is the ability of items of electronic equipment to function
properly together in the electronic environment. While this computer has been designed and
determined to be compliant with regulatory agency limits for EMI, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
interference with radio communications services, 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.
• Plug the computer into a different outlet so that the computer and the receiver are on
different branch circuits.
If necessary, consult a Dell Technical Support representative or an experienced
radio/television technician for additional suggestions.
