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, ( ), your system is considered to be a
Class B digital device.
Once you have determined your system’s FCC classification, read the appropriate FCC notice. Note
that FCC regulations provide that changes or modifications not expressly approved by Dell Com-
puter Corporation could void your authority to operate this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions:
•
This device may not cause harmful interference.
•
This device must accept any interference received, including interference that may cause
undesired operation.
Class A
This equipment has been tested and found to comply with the limits for a Class A digital device pur-
suant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance
with the manufacturer’s instruction manual, may cause harmful interference with radio communica-
tions. Operation of this equipment in a residential area is likely to cause harmful interference, in
which case you will be required to correct the interference at your own expense.
