DELL CONFIDENTIAL – PRELIMINARY 12/2/03 - FOR PROOF ONLY
116 Appendix
COMMENT: CLIENT WRITERS: Always verify with your
Regulatory engineer whether your platform is Class A or Class
B. If your Regulatory engineer confirms that your platform is
Class B only, you can delete all references to Class A in this
boilerplate.
• 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/sna/category.asp?category_id=4117.
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, see 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, side, 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.
