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 (EMC) 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.
Dell™ computers are designed, tested, and classified for their intended electromagnetic environment. These
electromagnetic environment classifications generally refer to the following harmonized definitions:
Class A is typically for business or industrial environments.
Class B is typically for residential environments.
Information Technology Equipment (ITE), including devices, expansion cards, printers, input/output (I/O)
devices, monitors, and so on, that are integrated into or connected to the computer should match the
electromagnetic environment classification of the computer.
