by receipts or other documentation. National Instruments will, at its option, repair or replace equipment that proves to be defective during the 
warranty period. This warranty includes parts and labor. 

The media on which you receive National Instruments software are warranted not to fail to execute programming instructions, due to defects in 
materials and workmanship, for a period of 90 days from date of shipment, as evidenced by receipts or other documentation. National Instruments 
will, at its option, repair or replace software media that do not execute programming instructions if National Instruments receives notice of such defects 
during the warranty period. National Instruments does not warrant that the operation of the software shall be uninterrupted or error free.

A Return Material Authorization (RMA) number must be obtained from the factory and clearly marked on the outside of the package before any 
equipment will be accepted for warranty work. National Instruments will pay the shipping costs of returning to the owner parts which are covered by 
warranty.
