Regulatory Information
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, 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 device 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 device with respect to the receiver.
Move the device away from the receiver.
Plug the device into a different outlet so that the device 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™ devices are designed, tested, and classified for their intended electromagnetic environment.
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 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/category.asp?
