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 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 computer systems, 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 system 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:
• 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, contact Dell™ Support or an experienced radio/television technician for additional suggestions.
Dell™ products are designed, tested, and classified for their intended electromagnetic environment. These electromagnetic
environment classifications generally refer to the following harmonized definitions:
• Class A is typically for business environments. Class B products may also be utilized in a Class A environment.
• Class B is typically for residential environments. Class A products should not be utilized in a Class B environment.
Information Technology Equipment (ITE), including peripherals, expansion cards, printers, input/output (I/O) devices,
monitors, and so on, that are integrated into or connected to the system should match the electromagnetic environment
classification of the computer system.
A Notice about Shielded Signal Cables: Use only shielded cables for connecting peripherals 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 www.dell.com.
Dell has determined that this product is a Class B harmonized product. The following sections provide country-specific
EMC/EMI or product safety information.
