Using this Yamaha CP5 stage piano is easy. First, connect the correct power supply to start it up. Then, plug in the sustain pedal to add expression to your playing. When using it, make sure to place it on a stable surface. Since one of the knob covers is missing, be careful not to damage the exposed knob. For maintenance, keep it in a dry and clean place. Wipe it gently with a soft cloth regularly to keep it looking good and functioning well.
