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 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.
Information Technology Equipment (ITE), including devices, expansion cards, printers, input/output (I/O)
devices, monitors, and so on, that are integrated into or connected to the computer should match the
electromagnetic environment classification of the computer.
A Notice About Shielded Signal Cables: Use only shielded cables for connecting devices 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 computers 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 computer 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 computers are classified by the Federal Communications Commission (FCC) as Class B digital devices.
To determine which classification applies to your computer, 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 computer 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 computer
is considered to be a Class B digital device.
