Warranty
3M warrants our instruments to be free from defects in materials and workmanship for one year under
normal conditions of use and service. For United States customers, we will replace or repair (our
option) defective instruments at no charge, excluding batteries, abuse, misuse, alterations, physical
damage, or instruments previously repaired by other than 3M. Microphones, sensors, printers, and
chart recorders may have shorter or longer warranty periods. This warranty states our total obligation
in place of any other warranties expresses or implied. Our warranty does not include any liability or
obligation directly resulting from any defective instrument or product or any associated damages,
injuries, or property loss, including loss of use or measurement data.
For warranty outside the United States, a minimum of one year warranty applies, subject to the same
limitation and exceptions as above with service provided or arranged through the authorized 3M
distributor or our 3M European Service Laboratory. Foreign purchases should contact the local 3M
authorized sales distributors for details.
