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 device 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 device with respect to the receiver.
• Move the device away from the receiver.
• Plug the device into a different outlet so that the device 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™ devices 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 or industrial environments.
• 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
device should match the electromagnetic environment classification of the device.
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.
