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 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 Technical Support representative of Dell or an experienced
radio/television technician for additional suggestions. You may find the FCC
Interference Handbook, 1986, to be helpful. It is available from the U.S.
Government Printing Office, Washington, DC 20402, Stock No. 004-000-00450-7 or
on the World Wide Web at http://www.fcc.gov/cib/Publications/tvibook.html.
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 for business or industrial environments.
•
Class B is for residential environments.
Information Technology Equipment (ITE), including peripherals, expansion cards,
printers, input/output (I/O) devices, monitors, and so on, that are integrated into or
connected to the system should match the electromagnetic environment
classification of the computer system.
A Notice About Shielded Signal Cables: Use only shielded cables for
connecting peripherals to any Dell device to reduce the possibility of
interference with radio communications services. Using shielded cables
ensures that you maintain the appropriate EMC classification for the
intended environment. For parallel printers, a cable is available from Dell.
If you prefer, you can order a cable from Dell on the World Wide Web at

Most Dell computer systems are classified for Class B environments. To determine
the electromagnetic classification for your system or device, refer to the following
sections specific for each regulatory agency. Each section provides country-specific
EMC/EMI or product safety information.
FCC Notices (U.S. Only)
Most Dell computer systems are classified by the Federal Communications
Commission (FCC) as Class B digital devices. However, the inclusion of certain
options can change the rating of some configurations to Class A. To determine which
classification applies to your computer system, examine all FCC registration labels
