Most Dell computer systems are classified by the Voluntary Control Council for Inter-
ference (VCCI) as Class B information technology equipment (ITE). However, the
inclusion of certain options changes the rating of some configurations to Class A. To
determine which classification applies to your computer system, examine the FCC
classification on the registration labels located on the back panel of y our c omput er, on
card-mounting brackets, and on the cards themselves. If any one of the labels carries
an FCC Class A designation, your entire system is considered to be VCCI Class A ITE.
If
all
labels carry either an FCC Class B identification number or the FCC logo ( ),
your system is considered to be VCCI Class B ITE.
Once you have determined your system’s VCCI classification, read the appropriate
VCCI notice. Note that VCCI regulations provide that changes or modifications not
expressly approved by Dell Computer Corporation could v oid y our authori ty to operate
this equipment.
