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.

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.
