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 computer systems, 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 system 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 radio, TV or other receiver away from the switch.
• Plug the Ethernet switch into a different power outlet so that the
switch and the receiver are on different branch circuits.
• If necessary, consult the place of purchase or an experienced
radio/television technician for additional suggestions.
If necessary, consult a Dell Technical Support representative or an
experienced radio/television technician for additional suggestions.
Dell computer systems 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.
