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 Quest
Technologies. 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 Quest distributor or our Quest European Service Laboratory. Foreign purchases
should contact the local Quest authorized sales agent for details.
