Additional instructions cover loading songs from a computer, using preset song collections (e.g., “50 greats for the Piano”), and adjusting parameters such as voice, reverb depth, and dual‑tone volume. The document includes diagrams of the highlighted keys and notes on the piano’s control layout. This manual is written in Chinese.
