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.
