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, I/O devices, monitors, and so on, that are integrated into or
connected to the computer should match the electromagnetic environment
classification of the computer.
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 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 at
accessories.us.dell.com/sna/segmenter/asp.
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 computer
or device, refer to the following sections specific for each regulatory agency.
Each section provides country-specific EMC/EMI or product safety
information.
