1-12 Dell Latitude L400 Advanced Port Replicator User’s Guide
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.
FCC Notices (U.S. Only)
Most Dell computer systems are classified by the Federal Communications Commis-
sion (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 con-
sidered 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 con-
sidered 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.
