Regulatory Notices
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.
