BW Technologies authorized resellers shall extend this warranty on new and unused products to end-user customers only but have no authority to extend a
greater or different warranty on behalf of BW Technologies. Warranty support is available if product is purchased through a BW Technologies authorized sales

when product purchased in one country is submitted for repair in another country.
BW Technologies’ warranty obligation is limited, at BW Technologies’ option, to refund of the purchase price, free of charge repair, or replacement of a defective

LIABLE FOR ANY SPECIAL, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES OR LOSSES, INCLUDING LOSS OF DATA, WHETHER ARISING
FROM BREACH OF WARRANTY OR BASED ON CONTRACT, TORT, RELIANCE OR ANY OTHER THEORY.
Since some countries or states do not allow limitation of the term of an implied warranty, or exclusion or limitation of incidental or consequential damages, the
limitations and exclusions of this warranty may not apply to every buyer. If any provision of this Warranty is held invalid or unenforceable by a court of competent
jurisdiction, such holding will not affect the validity or enforceability of any other provision.
