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. Cables are available from Dell at www.dell.com.
Most Dell devices 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
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 devices are classified by the Federal Communications Commission (FCC) as Class B digital devices.
To determine which classification applies to your device, examine all FCC registration labels located on the
bottom, side, or back panel of your device, on card-mounting brackets, and on the cards themselves. If any
one of the labels carries a Class A rating, your entire device 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, (
device is considered to be a Class B digital device.
Once you have determined your device's FCC classification, read the appropriate FCC notice. Note that FCC
regulations provide that changes or modifications not expressly approved by Dell 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
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. 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. 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.
