Appendix 141Dell computers are designed, tested, and classified for their intendedelectromagnetic environment. These electromagnetic environmentclassifications 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, expansioncards, printers, input/output (I/O) devices, monitors, and so on, that areintegrated into or connected to the computer should match theelectromagnetic environment classification of the computer.A Notice About Shielded Signal Cables: Use only shielded cables forconnecting devices to any Dell device to reduce the possibility ofinterference with radio communications services. Using shielded cablesensures that you maintain the appropriate EMC classification for theintended 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 computers are classified for Class B environments. However, theinclusion of certain options can change the rating of some configurations toClass A. To determine the electromagnetic classification for your computeror device, refer to the following sections specific for each regulatory agency.Each section provides country-specific EMC/EMI or product safetyinformation.For additional regulatory information, see the Tell Me How help file thataccompanied your computer.
