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, airtraffic 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
