Warranty and Return Policy
Dell Computer Corporation ("Dell") manufactures its hardware products from parts and components that are new or equivalent to new in accordance with
industry-standard practices. For information about the Dell™ warranty for your computer, see the Owner's Manual.
Regulatory Notices
Electromagnetic Interference (EMI) is any signal or emission, radiated in free space or conducted along power or signal leads, that endangers the functioning
of a radio navigation or other safety service or seriously degrades, obstructs, or repeatedly interrupts a licensed radio communications service. Radio
communications services include but are not limited to AM/FM commercial broadcast, television, cellular services, radar, air-traffic control, pager, and Personal
Communication Services (PCS). These licensed services, along with unintentional radiators such as digital devices, including computers, contribute to the
electromagnetic environment.
Electromagnetic Compatibility (EMC) is the ability of items of electronic equipment to function properly together in the electronic environment. While this
computer has been designed and determined to be compliant with regulatory agency limits for EMI, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause interference with radio communications services, 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:
l Reorient the receiving antenna.
l Relocate the computer with respect to the receiver.
l Move the computer away from the receiver.
l Plug the computer into a different outlet so that the computer and the receiver are on different branch circuits.
If necessary, consult a Dell Technical Support representative or an experienced radio/television technician for additional suggestions.
Dell™ computers are designed, tested, and classified for their intended electromagnetic environment. These electromagnetic environment classifications
generally refer to the following harmonized definitions:
l Class A is typically for business or industrial environments.
l Class B is typically for residential environments.
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. For
parallel printers, a cable is available from Dell. If you prefer, you can order a cable from Dell on the World Wide Web at
accessories.us.dell.com/sna/category.asp?category_id=4117.
Most Dell computers 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 computer or 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 computers are classified by the Federal Communications Commission (FCC) as Class B digital devices. To determine which classification applies to
your computer, examine all FCC registration labels located on the bottom, side, 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 computer 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, (
), your computer is considered to be a Class B digital device.
