WARNING REGARDING USE OF NATIONAL INSTRUMENTS PRODUCTS
YOU ARE ULTIMATELY RESPONSIBLE FOR VERIFYING AND VALIDATING THE SUITABILITY AND RELIABILITY OF THE
PRODUCTS WHENEVER THE PRODUCTS ARE INCORPORATED IN YOUR SYSTEM OR APPLICATION, INCLUDING THE
APPROPRIATE DESIGN, PROCESS, AND SAFETY LEVEL OF SUCH SYSTEM OR APPLICATION.
PRODUCTS ARE NOT DESIGNED, MANUFACTURED, OR TESTED FOR USE IN LIFE OR SAFETY CRITICAL SYSTEMS, HAZARDOUS
ENVIRONMENTS OR ANY OTHER ENVIRONMENTS REQUIRING FAIL-SAFE PERFORMANCE, INCLUDING IN THE OPERATION OF
NUCLEAR FACILITIES; AIRCRAFT NAVIGATION; AIR TRAFFIC CONTROL SYSTEMS; LIFE SAVING OR LIFE SUSTAINING
SYSTEMS OR SUCH OTHER MEDICAL DEVICES; OR ANY OTHER APPLICATION IN WHICH THE FAILURE OF THE PRODUCT OR
SERVICE COULD LEAD TO DEATH, PERSONAL INJURY, SEVERE PROPERTY DAMAGE OR ENVIRONMENTAL HARM
(COLLECTIVELY, “HIGH-RISK USES”). FURTHER, PRUDENT STEPS MUST BE TAKEN TO PROTECT AGAINST FAILURES,
INCLUDING PROVIDING BACK-UP AND SHUT-DOWN MECHANISMS. NI EXPRESSLY DISCLAIMS ANY EXPRESS OR IMPLIED
WARRANTY OF FITNESS OF THE PRODUCTS OR SERVICES FOR HIGH-RISK USES.
Compliance
Electromagnetic Compatibility Information
This hardware has been tested and found to comply with the applicable regulatory requirements and limits for electromagnetic
compatibility (EMC) as indicated in the hardware’s Declaration of Conformity (DoC)1. These requirements and limits are
designed to provide reasonable protection against harmful interference when the hardware is operated in the intended
electromagnetic environment. In special cases, for example when either highly sensitive or noisy hardware is being used in close
proximity, additional mitigation measures may have to be employed to minimize the potential for electromagnetic interference.
While this hardware is compliant with the applicable regulatory EMC requirements, there is no guarantee that interference will
not occur in a particular installation. To minimize the potential for the hardware to cause interference to radio and television
reception or to experience unacceptable performance degradation, install and use this hardware in strict accordance with the
instructions in the hardware documentation and the DoC1.
If this hardware does cause interference with licensed radio communications services or other nearby electronics, which can be
determined by turning the hardware off and on, you are encouraged to try to correct the interference by one or more of the
following measures:
•
•
•
Some hardware may require the use of a metal, shielded enclosure (windowless version) to meet the EMC requirements for
special EMC environments such as, for marine use or in heavy industrial areas. Refer to the hardware’s user documentation and
the DoC1 for product installation requirements.
When the hardware is connected to a test object or to test leads, the system may become more sensitive to disturbances or may
cause interference in the local electromagnetic environment.
Operation of this hardware in a residential area is likely to cause harmful interference. Users are required to correct the
interference at their own expense or cease operation of the hardware.
Changes or modifications not expressly approved by National Instruments could void the user’s right to operate the hardware
under the local regulatory rules.
Reorient the antenna of the receiver (the device suffering interference).
Relocate the transmitter (the device generating interference) with respect to the receiver.
Plug the transmitter into a different outlet so that the transmitter and the receiver are on different branch circuits.
1 The Declaration of Conformity (DoC) contains important EMC compliance information and instructions for the user or
installer. To obtain the DoC for this product, visit ni.com/certification, search by model number or product line, and
click the appropriate link in the Certification column.
