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
the Class B rating, 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
NOTE: 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
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 interfer-
ence at your own expense.
Class B
NOTE: 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 interference with radio and television recep-
tion. This equipment has been tested and found to comply
with the limits for a Class B digital device pursuant to
Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interfer-
ence in a residential installation. However, there is no
guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful inter-
ference with radio or television reception, which can be
determined by turning the equipment off and on, you are
encouraged to try to correct the interference by one or
more of the following measures:
•
Reorient the receiving antenna.
•
Relocate the computer with respect to the receiver.
•
Move the computer away from the receiver.
•
Plug the computer into a different outlet so that the
computer and the receiver are on different branch
circuits.
If necessary, consult a representative of Dell Computer
Corporation or an experienced radio/television technician
for additional suggestions. You may find the following
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.
