A factory reset returns the Roland JX-08 to its factory settings. Turn on the power while holding down the PART [B] button, then press the blinking [PAGE/TIE] button. When “donE” appears, turn the power off and then on again.
Note: A factory reset erases all user data. Back up important data first.
For details, refer to “Restoring the Factory Settings (Factory Reset)” and “Backing Up Data” in the JX-08 Reference Manual.
