When this function is turned off, the keyboard does not
turn off automatically no matter how long it is left with

turn off power and then turn it back on again.
Memory Contents
Registration memory contents, recorder memory contents,
and song bank data you transfer from a computer to keyboard
memory are all retained when the keyboard is turned off,
either by pressing the power button or by Auto Power Off.
Electrical Power
The memory contents described above are retained as long
as the keyboard is being supplied with electrical power.

the AC adaptor before replacing its batteries.
Before unplugging the AC adaptor, make sure that fresh
