Your serial number is located on the cover of the printed Users Guide that came with your instrument. If you purchased your instrument from our webstore, your serial number will be located on your receipt. It's very important that you keep this number, as it gives you access to all updates and support for your Spectrasonics instrument. 

Our User Account system allows you access to your serials 24 hours a day. If you haven't yet created a User Account, please do so and add your serial numbers to it for future access. 

If you've lost your User's Guide and/or can't log in to your User Account, please contact us directly and we'll be able to help you.
