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

Most Dell computers are classified for Class B environments. To determine
the electromagnetic classification for your computer or device, refer to 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. However, the inclusion of
certain options can change the rating of some configurations to Class A. To
determine which classification applies to your computer, 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 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.
