FCC/DOC Radio Frequency Interference Compliance
This equipment generates and uses radio frequency energy and, if not installed and used in strict accordance with the
instructions in this manual, may cause interference to radio and television reception. This equipment has been tested
and found to comply with the following two regulatory agencies:
•
The limits for a Class A computing device, in accordance with the specifications in Part 15 of U.S. Federal
Communications Commission (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.
•
The limits for radio noise emissions from digital apparatus set out in the Radio Interference Regulations of the
Canadian Department of Communications (DOC).
These regulations are designed to provide reasonable protection against interference from the equipment to radio and
television reception in commercial areas.
There is no guarantee that interference will not occur in a particular installation. However, the chances of
interference are much less if the equipment is used according to this instruction manual.
If the equipment does cause interference to radio or television reception, which can be determined by turning the
equipment on and off, one or more of the following suggestions may reduce or eliminate the problem.
•
Operate the equipment and the receiver on different branches of your AC electrical system.
•
Move the equipment away from the receiver with which it is interfering.
•
Relocate the equipment with respect to the receiver.
•
Reorient the receiver's antenna.
•
Be sure that the equipment is plugged into a grounded outlet and that the grounding has not been defeated with
a cheater plug.
Notice to user: Changes or modifications not expressly approved by National Instruments could void the user's
authority to operate the equipment under the FCC Rules.
If necessary, consult National Instruments or an experienced radio/television technician for additional suggestions.
The following booklet prepared by the FCC may also be helpful: How to Identify and Resolve Radio-TV
Interference Problems. This booklet is available from the U.S. Government Printing Office, Washington, DC
