Connect the provided charger to the piano's power input port and then to a standard electrical outlet (220V input voltage). The piano has a built-in 1000 mAh battery. A full charge takes approximately 4 hours and provides 10 to 12 hours of playing time. Press the power button to turn the piano on or off.

3. Connecting the Sustain Pedal
Locate the sustain pedal input port on the piano (labeled "SUS"). Insert the pedal's cable firmly into this port. The sustain pedal allows you to prolong the sound of notes, similar to an acoustic piano.
4. Music Stand and Anti-slip Pads
The piano includes a practical music stand that can be attached to hold sheet music or a tablet. Ensure the anti-slip foot pads on the bottom of the piano are properly positioned to prevent movement during play.
