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 ser vice or seriously degrades, obstructs, or repeatedly   
interrupts a licensed radio communications ser vice. Radio communications ser vices 
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 tr y 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 Technical Support representative of Dell Computer Corporation 
or an experienced radio/television technician for additional suggestions. You may find 
the FCC Interference Handbook, 1986, to be helpful. It is available from the U.S.    
Government Printing Office, Washington, DC 20402, Stock No. 004-000-00450-7 or 
on the World Wide Web at 
http://www.fcc.gov/Bureaus/Compliance/WWW/

Dell computer systems 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 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.

Most Dell computer systems are classified by the Federal Communications           
Commission (FCC) as Class B digital devices. However, the inclusion of certain 
options can change the rating of some configurations to Class A. To determine which 
classification applies to your computer system, examine all FCC registration labels 
located on the bottom or back panel of your computer, on card-mounting brackets, 
and on the cards themselves. If any one of the labels carries a Class A rating, your 
entire system is considered to be a Class A digital device. If all
 labels carry an FCC 
Class B rating as distinguished by either an FCC ID number or the FCC logo, ( ), 
your system is considered to be a Class B digital device.
Once you have determined your system’s FCC classification, read the appropriate 
FCC notice. Note that FCC regulations provide that changes or modifications not 
expressly approved by Dell Computer Corporation could void your authority to operate 
this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the        
following two conditions:

This device may not cause harmful interference.

This device must accept any interference received, including interference that 
may cause undesired operation.

The equipment should draw power from a socket with an attached protection circuit  
(a three-prong socket). All equipment that works together (computer, monitor, printer, 
and so on) should have the same power supply source.
The phasing conductor of the room’s electrical installation should have a reserve 
short-circuit protection device in the form of a fuse with a nominal value no larger  
than 16 amperes (A). 
To completely switch off the equipment, the power supply cable must be removed 
from the power supply socket, which should be located near the equipment and easily 
accessible. 
A protection mark “B” confirms that the equipment is in compliance with the         
protection usage requirements of standards PN-93/T-42107 and PN-89/E-06251.
