Most Dell computer systems are classified by the Federal
Communications Commission (FCC) as Class B digital
devices. However, the inclusion of certain options
changes the rating of some configurations to Class A. To
determine which classification applies to your computer
system, examine all FCC registration labels located on
the 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 con-
sidered to be a Class A digital device. If all labels carry
either the Class B rating or the FCC logo (
), your sys-
tem is considered to be a Class B digital device.
NOTE: Some Dell computer systems that are classified as
Class B digital devices may include a built-in network
interface controller (NIC). If your system contains a NIC,
it is considered to be a Class A digital device only at the
time that the NIC is being used. When the NIC is not
being used, your system is considered to be a Class B
digital device.
Once you have determined your system’s FCC classifica-
tion, read the appropriate FCC notice. Note that FCC
regulations provide that changes or modifications not
expressly approved by Dell Computer Corporation could
void your authority to operate this equipment.
Class A
This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accor-
dance with the manufacturer’s instruction manual, may
cause harmful interference with radio communications.
This equipment has been tested and found to comply with
the limits for a Class A digital device pursuant 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.
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.
A Notice About Shielded Cables: Use only shielded
cables for connecting peripherals to any Dell device
to reduce the possibility of interference with radio
and television reception. Using shielded cables
ensures that you maintain the appropriate FCC
radio frequency emissions compliance (for a Class
A device) or FCC certification (for a Class B
device) of this product. For parallel printers, a
cable is available from Dell Computer
Corporation.
