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 commer­
cial broadcast, television, cellular services, radar,
air-traffic control, pager, and Personal Communication
Services (PCS). These licensed services, along with unin­
tentional 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 com­
puter 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 particu­
lar installation. If this equipment does cause interference
with radio communications services, which can be deter­
mined 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.

Dell computer systems are designed, tested, and classi­
fied for their intended electromagnetic environment.
These electromagnetic environment classifications gen­
erally 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 electromag­
netic 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 avail­
able 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.
A Notice About Networked Computer Systems:
Some Dell computer systems that are classified for
Class B environments may include an on-board
network interface controller (NIC). If your Class B
system contains a NIC, it may be considered to be a
Class A system at the time that the NIC is con­
nected to a network. When the NIC is not
connected to a network, your system is considered
to be a Class B digital device.
Most Dell computer systems are classified for Class B
environments. To determine the electromagnetic classifi­
cation 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.
