Here's how to load a backup that you have previously saved to a USB Memory drive into the TD-15.
Caution: Loading a backup from a USB memory drive erases ALL user settings in the TD-15. Be sure to perform a backup of your current settings first, if you want to keep them.
1. Insert your USB memory drive into the TD-15's USB Memory port.
2. Press MENU.
3. Press the cursor down button until the SYSTEM icon appears.
4. Press the function 3 button (SYSTEM).
5. Press cursor down to select "USB Memory," and then press function 3 (ENTER).
6. Press the cursor down button to select "Load Backup," and then press function 3 (ENTER).
7. Turn the dial to choose the desired backup number that you want to load.
8. Press function 3 (LOAD). "Load Backup . Are you sure?" appears.
9. Press function 3 (OK).
