E About the backup memory
The selected sound and various functions, MIDI settings and SEQUENCER contents remain in the memory for
about one week after the POWER is turned off.
The backup memory does not function until the POWER has been on for about 10 minutes. i
If you would like the memory contents to be retained for more than one week, turn the power on once before
the week-long period is about to expire, leave the piano in this condition for about ten minutes, and then turn
the power back off again. The memory backup function will start operating for one more week from that point.
If you wish to return all memories and settings to their initialized status, while pressing the MODE SET button,
press the INITIAL key on the keyboard. Or you can turn on the POWER while pressing the INITIAL key.
When the POWER is turned on, the MIDI LOCAL CONTROL is set to on.
