Dell Latitude L400 System Information Guide 1-13
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 for business or industrial environments.
• Class B is for residential environments.
Information Technology Equipment (ITE), including peripherals, expansion cards, print-
ers, input/output (I/O) devices, monitors, and so on, that are integrated into or
connected to the system should match the electromagnetic environment classifica-
tion of the computer system.

Most Dell computer systems are classified for Class B environments. To determine
the electromagnetic classification for your system or device, refer to the following
sections specific for each regulatory agency. Each section provides country-specific
EMC/EMI or product safety information.

Most Dell computer systems are classified by the Federal Communications
Commission (FCC) as Class B digital devices. However, the inclusion of certain
options can change the rating of some configurations to Class A. To determine which
classification applies to your computer system, examine all FCC registration labels
located on the bottom or back panel of your computer, on card-mounting brackets, and
on the cards themselves. If any one of the labels carries a Class A rating, your entire
system is considered to be a Class A digital device. If
all
labels carry an
FCC Class B rating as distinguished by either an FCC ID number or the FCC logo,
( ), your system is considered to be a Class B digital device.
Once you have determined your system’s FCC classification, read the appropriate
FCC notice. Note that FCC regulations provide that changes or modifications not
expressly approved by Dell could void your authority to operate this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the follow-
ing two conditions:
• This device may not cause harmful interference.
• This device must accept any interference received, including interference that
may cause undesired operation.
