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 expressed 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
purchasers should contact the local 3M authorized sales agent for detail.
