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 Technical Support 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.

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 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.
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
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 Computer Corporation could void your authority to operate
this equipment.
This device complies with Part 15 of the FCC Rules. Operation is

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.
