Fcc Notices (U.s. Only) - Dell Precision M50 System Information Manual

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
accessories.us.dell.com/.
Most Dell computers 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 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. 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
