Appendix C
Dell computers 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 system must match the electromagnetic
environment classification of the system.
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 Electromagnetic Compatibility classification for the
intended environment. Cables are available from Dell at dell.com.
Most Dell computers are classified for Class B environments. However, the
inclusion of certain options can change the rating of some configurations to
Class A. To determine the electromagnetic classification for your system or
device, see the following sections specific for each regulatory agency. Each
section provides country-specific Electromagnetic Compatibility/EMI or
product safety information.
