Yes, this is certainly possible. To do this, first go to the Two Notes Store website which can be found at the following link:
If you haven't already, log into your account by going to the menu in the top right hand corner of the screen.
Once you are logged in, click on the same menu and select Manage your License and Two Notes Products.
You should now see your Sono registered to your account. To de-register it, simply click the De-register button. This Sono will then be removed from your account. Please note when the Sono is de-registered, the cabinets included with Sono will also be removed from your account.
To re-register this unit to another account, you would need to just open the torpedo remote software and log-in using the account you wish to register the Sono on. When the Sono is selected from the device rack, you'll be prompted to register the device to your account. Follow these steps through to finalise the Registration.
