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
