Appendix 131
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:
• 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 regulatory information, see the Tell Me How help file that accompanied your 
computer. To access the help file, see page 32.
