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:

This device complies with Part 15 of the Federal Communications Commission (FCC) Rules for a Class A digital

device. Operation is subject to the following two conditions:

1. This device may not cause harmful interference in commercial environments.

2. This device must accept any interference received, including interference that may cause undesired operation.

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 A prescrites dans le règlement sur le brouillage radioélectrique édicté par le ministère des

communications du Canada.

These regulations are designed to provide reasonable protection against harmful interference from the equipment to

radio reception in commercial areas. Operation of this equipment in a residential area is likely to cause harmful

interference, in which case the user will be required to correct the interference at his own expense.

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.
