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 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, consult a Dell Technical Support representative or an experienced
radio/television technician for additional suggestions. For additional information, see the
User’s Guide that accompanied your computer.
NOTE: Inspect the regulatory label affixed to the back or bottom of your Dell System to
determine the environments in which your system may be operated.
