Back to Contents PageRegulatory NoticesDell™ OptiPlex™ GX60 Systems User's GuideElectromagnetic Compatibility (EMC) is the ability of items of electronic equipment to function properly together in the electronic environment. While thiscomputer system has been designed and determined to be compliant with regulatory agency limits for EMI, there is no guarantee that interference will notoccur in a particular installation. If this equipment does cause interference with radio communications services, which can be determined by turning theequipment off and on, you are encouraged to try to correct the interference by one or more of the following measures:l Reorient the receiving antenna.l Relocate the computer with respect to the receiver.l Move the computer away from the receiver.l 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.Dell™ computer systems are designed, tested, and classified for their intended electromagnetic environment. These electromagnetic environmentclassifications generally refer to the following harmonized definitions:l Class A is typically for business or industrial environments.l 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 integratedinto 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 interferencewith radio communications services. Using shielded cables ensures that you maintain the appropriate EMC classification for the intended environment.For parallel printers, a cable is available from Dell. If you prefer, you can order a cable from Dell on the World Wide Web ataccessories.us.dell.com/sna/category.asp?category_id=4117.Most Dell computer systems are classified for Class B environments. However, the inclusion of certain options can change the rating of some configurations toClass A. To determine the electromagnetic classification for your system or device, see the following sections specific for each regulatory agency. Each sectionprovides country-specific EMC/EMI or product safety information.FCC Notices (U.S. Only)Most Dell computer systems are classified by the Federal Communications Commission (FCC) as Class B digital devices. To determine which classificationapplies to your computer system, examine all FCC registration labels located on the bottom, side, 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 carryan 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 modificationsnot expressly approved by Dell 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:l This device may not cause harmful interference.l This device must accept any interference received, including interference that may cause undesired operation.Class AThis equipment has been tested and found to comply with the limits for a Class A digital device pursuant to Part 15 of the FCC Rules. These limits are designedto provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses,and can radiate radio frequency energy and, if not installed and used in accordance with the manufacturer's instruction manual, may cause harmfulinterference with radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case you will berequired to correct the interference at your own expense.
