Warranty Repair 
Dave Smith Instruments warrants that Tetra will be free from defects in 
materials and/or workmanship for 1 year from the date of purchase. Please 
register your product online at www.davesmithinstruments.com to establish the 
date of purchase. (This is not a requirement for warranty service, but it will help 
expedite the process.) 
Please contact support@davesmithinstruments.com to determine the best course 
of action for getting your Tetra repaired. For your own protection, as well as 
ours, please do not return any product to Dave Smith Instruments without a 
return authorization (RA) number. To issue an RA number, Technical 
Support needs: 
•  Your name 
•  Your return address 
•  Your email address 
•  A phone number where you can be reached 
•  Your Tetra’s serial number 
•  The date of purchase and where purchased 
If you need to return your instrument for repair, you are responsible for getting it 
to DSI. We highly recommend insuring it and packing in the original packaging. 
Damage resulting from shipping a product with insufficient packaging is not 
covered by warranty.
