Warning Regarding Medical and Clinical Use

of National Instruments Products

National Instruments products are not designed with components and testing intended to ensure a level of reliability

suitable for use in treatment and diagnosis of humans. Applications of National Instruments products involving

medical or clinical treatment can create a potential for accidental injury caused by product failure, or by errors on

the part of the user or application designer. Any use or application of National Instruments products for or involving

medical or clinical treatment must be performed by properly trained and qualified medical personnel, and all

traditional medical safeguards, equipment, and procedures that are appropriate in the particular situation to prevent

serious injury or death should always continue to be used when National Instruments products are being used.

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 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.

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 A 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 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.

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.
