Overview
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 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 Regulatory EMC representative of Dell Computer Corporation 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/Bureaus/Compliance/WWW/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 Computer Corporation. If you
prefer, you can order a cable from Dell Computer Corporation on the World Wide Web at http://www.dell.
com/products/dellware/index.htm.
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.
