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 Dell Technical Support representative or an experienced radio/television technician for additional
suggestions.
For additional regulatory information, see the Product Information Guide that came with your computer.
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.
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
accessories.us.dell.com/sna/category.asp?category_id=4117.
Most Dell computer systems are classified for Class B environments. However, the inclusion of certain options can change
the rating of some configurations to Class A. To determine the electromagnetic classification for your system or device, see
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.
To determine which classification applies to your computer system, examine all FCC registration labels located on the
bottom, side, or back panel of your computer, on card-mounting brackets, and on the cards themselves. If any one of the
labels carries a Class A rating, your entire system is considered to be a Class A digital device. If all labels carry an FCC
Class B rating as distinguished by either an FCC ID number or the FCC logo, (

), your system is considered to be a Class
