All RY8/RY9 settings may be reset to their initial factory settings at any time. CAUTION: Initiating the Factory Set operation will clear all User Patterns, Songs and Drum Kits. Be sure to save any important User Data to an external MIDI data storage device. A computer with sequencing software such as Cubase by Steinberg is the usual choice.
Starting with the Power OFF:
1. Hold down the [-1] and [+1] buttons simultaneously, then switch the power ON.
2. The words "FACTRY SET" will appear momentarily on the LCD, and the RY8 will continue to boot normally.
