WARRANTY REPAIR POLICY
Limited Warranty on Products
Any Cooper Instruments product which, under normal operating conditions, proves defective in material or in
workmanship within one year of the date of shipment by Cooper will be repaired or replaced free of charge provided that a
return material authorization is obtained from Cooper and the defective product is sent, transportation charges prepaid,
with notice of the defect, and it is established that the product has been properly installed, maintained, and operated
within the limits of rated and normal usage. Replacement or repaired product will be shipped F.O.B. from our plant. The
terms of this warranty do not extend to any product or part thereof which, under normal usage, has an inherently shorter
