5. WARRANTY AND LIMITATION OF LIABILITY

This Martindale product is warranted to be free from defects in material 

and workmanship under normal use and service. The warranty period 

is 2 years and begins on the date of receipt by the end user. This 

warranty extends only to the original buyer or end-user customer, 

and does not apply to fuses, disposable batteries, test leads or to any 

product which, in Martindale’s reasonable opinion, has been misused, 

altered, neglected, contaminated, or damaged by accident or abnormal 

conditions of operation, handling or storage.  

Martindale authorised 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 Martindale.

Martindale’s warranty obligation is limited, at Martindale’s option, to refund 

of the purchase price, free of charge repair, or replacement of a defective 

product which is returned to Martindale within the warranty period.

This warranty is the buyer’s sole and exclusive remedy and is in lieu 

of all other warranties, expressed or implied, including but not limited 

to any implied warranty of merchantability or fitness for a particular 

purpose. Martindale shall not be liable for any special, indirect, incidental 

or consequential damages or losses, including loss of data, arising from 

any cause or theory.

Since some jurisdictions 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 part of any provision of this warranty is held invalid 

or unenforceable by a court or other decision-maker of competent

jurisdiction, such holding will not affect the validity or enforceability of 

any other provision or other part of that provision.

Nothing in this statement reduces your statutory rights.
