Appendix 109
Most Dell computer systems 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 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
Commission (FCC) as Class B digital devices. 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 following two conditions:
• This device may not cause harmful interference.
• This device must accept any interference received, including
interference that may cause undesired operation.
