User's Manual

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 radio

services, and unlicensed radio services, such as WLAN or Bluetooth, 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.

Dell™ products are designed, tested, and classified for their intended electromagnetic

environment. These electromagnetic environment classifications generally refer to the

following harmonized definitions:

• Class B products are intended for use in residential/domestic environments but

may also be used in non-residential/non-domestic environments.

Note: The residential/domestic environment is an environment where the use of

broadcast radio and television receivers may be expected within a distance of 10

m from where this product is used.

• Class A products are intended for use in non-residential/non-domestic

environments. Class A products may also be utilized in residential/domestic

environments but may cause interference and require the user to take adequate

corrective measures.

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 or EMC technician for additional suggestions.

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.
