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:

Federal Communications Commission

This device complies with Part 15 of the Federal Communications

Commission (FCC) Rules for a Class B digital device. A Class B device is

distinguishable from a Class A device by the appearance of an FCC ID

number located on the Class B device.

Canadian Department of Communications

This device complies with the limits for radio noise emissions from digital

apparatus set out in the Radio Interference Regulations of the Canadian

Department of Communications (DOC).

Le présent appareil numérique n’émet pas de bruits radioélectriques

dépassant les limites applicables aux appareils numériques de classe B

prescrites dans le règlement sur le brouillage radioélectrique édicté par le

ministère des communications du Canada.

Instructions to Users

These regulations are designed to provide reasonable protection against

interference from the equipment to radio and television reception in

residential 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 installed and 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.

• Reorient or relocate 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 20402, Stock Number 004-000-00345-4.
