OR IMPLIED WARRANTIES AS TO THE ACCURACY OF THE INFORMATION CONTAINED HEREIN AND 

SHALL NOT BE LIABLE FOR ANY ERRORS.
NI warrants that its hardware products will be free of defects in materials and workmanship that cause the product to fail to 

substantially conform to the applicable NI published specifications for one (1) year from the date of invoice.
For a period of ninety (90) days from the date of invoice, NI warrants that (i) its software products will perform substantially 

in accordance with the applicable documentation provided with the software and (ii) the software media will be free from 

defects in materials and workmanship.
If NI receives notice of a defect or non-conformance during the applicable warranty period, NI will, in its discretion: (i) repair 

or replace the affected product, or (ii) refund the fees paid for the affected product. Repaired or replaced Hardware will be 

warranted for the remainder of the original warranty period or ninety (90) days, whichever is longer. If NI elects to repair or 

replace the product, NI may use new or refurbished parts or products that are equivalent to new in performance and reliability 

and are at least functionally equivalent to the original part or product.
You must obtain an RMA number from NI before returning any product to NI. NI reserves the right to charge a fee for 

examining and testing Hardware not covered by the Limited Warranty.
This Limited Warranty does not apply if the defect of the product resulted from improper or inadequate maintenance, 

installation, repair, or calibration (performed by a party other than NI); unauthorized modification; improper environment; 

use of an improper hardware or software key; improper use or operation outside of the specification for the product; improper 

voltages; accident, abuse, or neglect; or a hazard such as lightning, flood, or other act of nature.
THE REMEDIES SET FORTH ABOVE ARE EXCLUSIVE AND THE CUSTOMER’S SOLE REMEDIES, AND SHALL 

APPLY EVEN IF SUCH REMEDIES FAIL OF THEIR ESSENTIAL PURPOSE.
EXCEPT AS EXPRESSLY SET FORTH HEREIN, PRODUCTS ARE PROVIDED "AS IS" WITHOUT WARRANTY OF 

ANY KIND AND NI DISCLAIMS ALL WARRANTIES, EXPRESSED OR IMPLIED, WITH RESPECT TO THE 

PRODUCTS, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A 

PARTICULAR PURPOSE, TITLE OR NON-INFRINGEMENT, AND ANY WARRANTIES THAT MAY ARISE FROM 

USAGE OF TRADE OR COURSE OF DEALING. NI DOES NOT WARRANT, GUARANTEE, OR MAKE ANY 

REPRESENTATIONS REGARDING THE USE OF OR THE RESULTS OF THE USE OF THE PRODUCTS IN TERMS 

OF CORRECTNESS, ACCURACY, RELIABILITY, OR OTHERWISE. NI DOES NOT WARRANT THAT THE 

OPERATION OF THE PRODUCTS WILL BE UNINTERRUPTED OR ERROR FREE.
