Compliance with FCC/Canada Radio Frequency Interference
Regulations
Determining FCC Class
The Federal Communications Commission (FCC) has rules to protect wireless communications from interference. The FCC
places digital electronics into two classes. These classes are known as Class A (for use in industrial-commercial locations only)
or Class B (for use in residential or commercial locations). All National Instruments (NI) products are FCC Class A products.
Depending on where it is operated, this Class A product could be subject to restrictions in the FCC rules. (In Canada, the
Department of Communications (DOC), of Industry Canada, regulates wireless inte rference in much the same way.) Digi tal
electronics emit weak signals during normal operation that can affect radio, television, or other wireless produ cts.
All Class A products display a simple warning statement of one paragraph in length regarding interference and un desired
operation. The FCC rules have restrictions regarding the locations where FCC Class A products can be operated .
Consult the FCC Web site at www.fcc.gov for more information.
FCC/DOC Warnings

Class A
Federal Communications Commission
This equipment has been tested and found to comply with the limits for a Class A dig ital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection against harmf ul interference when the equipment is operated
in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and
used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is lik ely to cause harmful interference in whic h case the user is req uired to correct the i nterference
at their own expense.
