Regulatory Notices
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 service or seriously degrades, obstructs, or
repeatedly interrupts a licensed radio communications service. Radio communications services 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 printers, 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 printer 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 try to correct the interference by one or more of the following measures:
• Reorient the receiving antenna.
• Relocate the printer with respect to the receiver.
• Move the printer away from the receiver.
• Plug the printer into a different outlet so that the printer 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™ printers 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 printer should match the electromagnetic environment
classification of the printer.
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/category.asp?category_id=4117.
Most Dell printers 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 printer or device, see
the following sections specific for each regulatory agency. Each section provides country-specific EMC/EMI or product
safety information.
