Dell Dimension 8100 Solution Manual page 83

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.
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. 004-000-00450-7 or on the World Wide Web at

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.
NOTICE: 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
