Section 411.214 - Exclusion or modification of warranties(1) Words or conduct relevant to the creation of an express warranty and words or conduct tending to negate or limit a warranty shall be construed wherever reasonable as consistent with each other; but, subject to s. 411.202, negation or limitation is inoperative to the extent that the construction is unreasonable.(2) Subject to sub. (3), to exclude or modify the implied warranty of merchantability or a part of it the language shall mention "merchantability", be by a writing and be conspicuous. Subject to sub. (3), to exclude or modify an implied warranty of fitness the exclusion shall be by a writing and be conspicuous. Language to exclude all implied warranties of fitness is sufficient if it is in writing, is conspicuous and states, for example, "There is no warranty that the goods will be fit for a particular purpose."(3) Notwithstanding sub. (2), but subject to sub. (4), all of the following apply: (a) Unless the circumstances indicate otherwise, all implied warranties are excluded by expressions such as "as is", or "with all faults", or by other language that in common understanding calls the lessee's attention to the exclusion of warranties and makes plain that there is no implied warranty, if in writing and conspicuous.(b) If the lessee before entering into the lease contract examines the goods or the sample or model as fully as desired or refuses to examine the goods, there is no implied warranty with regard to defects that an examination ought in the circumstances to have revealed.(c) An implied warranty may also be excluded or modified by course of dealing, course of performance, or usage of trade.(4) To exclude or modify a warranty against interference or against infringement or any part of that warranty, the language shall be specific, be by a writing, and be conspicuous, unless the circumstances, including course of performance, course of dealing, or usage of trade, give the lessee reason to know that the goods are being leased subject to a claim or interest of any person.
