ComplianceFCC/Canada Radio Frequency Interference Compliance*Determining FCC ClassThe 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). Depending on where it isoperated, this product could be subject to restrictions in the FCC rules. (In Canada, the Department ofCommunications (DOC), of Industry Canada, regulates wireless interference in much the same way.)Digital electronics emit weak signals during normal operation that can affect radio, television, or other wirelessproducts. By examining the product you purchased, you can determine the FCC Class and therefore which of the twoFCC/DOC Warnings apply in the following sections. (Some products may not be labeled at all for FCC; if so, thereader should then assume these are Class A devices.)FCC Class A products only display a simple warning statement of one paragraph in length regarding interference andundesired operation. Most of our products are FCC Class A. The FCC rules have restrictions regarding the locationswhere FCC Class A products can be operated.FCC Class B products display either a FCC ID code, starting with the letters EXN,or the FCC Class B compliance mark that appears as shown here on the right.Consult the FCC web site http://www.fcc.gov for more information.FCC/DOC WarningsThis equipment generates and uses radio frequency energy and, if not installed and used in strict accordance with theinstructions in this manual and the CE Mark Declaration of Conformity**, may cause interference to radio andtelevision reception. Classification requirements are the same for the Federal Communications Commission (FCC)and the Canadian Department of Communications (DOC).Changes or modifications not expressly approved by National Instruments could void the user’s authority to operatethe equipment under the FCC Rules.Class AFederal Communications CommissionThis equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when theequipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequencyenergy and, if not installed and used in accordance with the instruction manual, may cause harmful interference toradio communications. Operation of this equipment in a residential area is likely to cause harmful interference inwhich case the user will be required to correct the interference at his own expense.Canadian Department of CommunicationsThis Class A digital apparatus meets all requirements of the Canadian Interference-Causing Equipment Regulations.Cet appareil numérique de la classe A respecte toutes les exigences du Règlement sur le matériel brouilleur duCanada.Class BFederal Communications CommissionThis equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in aresidential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installedand used in accordance with the instructions, may cause harmful interference to radio communications. However,there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmfulinterference to radio or television reception, which can be determined by turning the equipment off and on, the useris encouraged to try to correct the interference by one or more of the following measures:• Reorient or relocate the receiving antenna.• Increase the separation between the equipment and receiver.
