Using this Roland RD - 300NX digital piano is easy. First, connect it to the included power supply. Then you can start playing right away. When using it, avoid placing it in a humid or dusty environment. If you notice any performance issues, check the power connection. For maintenance, wipe the piano with a soft, dry cloth regularly. Don't use harsh chemicals. And even though the 'High' knob cover is missing, you can still use the knob as normal. Just be a bit careful not to damage it.
