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 available from Dell Computer Corpora-
tion. 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 classi-
fied 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 connected to a network. When the NIC is not connected to a network, your sys-
tem is considered to be a Class B digital device.
Most Dell computer systems are classified for Class B environments. To determine the electromag-
netic classification 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.
FCC Notices (U.S. Only)
Most Dell computer systems 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 con-
figurations to Class A. To determine which classification applies to your computer system, 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
system is considered to be a Class A digital device. If all labels carry an FCC Class B rating as dis-
tinguished by either an FCC ID number or the FCC logo, (
