Some models have the auto-power off function. The piano (or keyboard) will turn off automatically to preserve power after a period of inactivity. To disable the auto-power off function, please refer to the users manual.
If the power turns off automatically even if the auto-power off function is disabled, or the power turns off soon after the power turned on, there may be any failure.
In such a case, please contact our authorized repair center. Please refer to the support page from the following URL to find our authorized repair center in your country or region.
