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.
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, refer to the following sections specific for each regulatory agency.
Each section provides country-specific EMC/EMI or product safety information.
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 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 B digital device.
Once you have determined your system's FCC classification, read the
appropriate FCC notice. Note that FCC regulations provide that changes or
modifications not expressly approved by Dell could void your authority to
operate this equipment.

be required to correct the interference at your own expense.
Class B
This equipment has been tested and found to comply with the limits for a
Class B digital device pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the
manufacturer's instruction manual, may cause interference with radio
communications. However, there is no guarantee that interference will not occur
in a particular installation. If this equipment does cause harmful interference
to radio or television reception, 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 or relocate the receiving antenna.
Increase the separation between the equipment and the receiver.
Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
Consult the dealer or an experienced radio/television technician for help.
