How do you reset a Yamaha keyboard?

There are two ways to reset a Yamaha keyboard:

1. Backup Reset (Will delete your playings saved in Backup Flash Memory)

Your keyboard should be turned off. Then, press the very right white key and hold it pressed while you turn on the keyboard (stand by button).

2. Flash Clean (Will delete everything you purchased and downloaded from a PC to your keyboard)

Your keyboard should be turned off. Then, press the very right white key PLUS THE closest 3 black keys to the mentioned white key and hold them pressed while you turn on the keyboard (stand by button).

This method works for most of Yamaha Keyboards.
