To fully restore the module to original factory settings, hold the EXIT and STORE buttons while powering on the module.
To reset only the kits, sequences, or trigger settings:

1. Press UTILITY to enter the main Utility Menu.
2. Press SYS (F4) to access the Accompaniment Settings.
3. Press INIT (F2) to access the reinitialization page.
4. Use CURSOR UP/DOWN to move through the following menu items:
   • All Kits: All of the module's kits and their settings will return to factory default
   • All Sequences: All of the module's sequences and their settings will return to factory default
   • All Trigger Settings: All of the module's trigger settings will return to factory default
5. Highlight the option you would like to reset, then press EXEC (F4).
6. A window will appear asking you to confirm your choice. To confirm and reinitialize the selected settings, press YES (F1). To Cancel, press CANCEL (F2 or F2).
