How to use

Connect the keyboard to a USB power source or a compatible USB power adapter, attach a sustain pedal to the pedal input if desired, and connect headphones or external speakers to the 1/4" output for private practice. Use the LCD and backlit buttons to select voices, songs or recording functions; play naturally on the touch‑sensitive keys to use dynamic response. For MIDI communication or powering from a computer, connect via the USB interface following your computer's MIDI/USB setup procedures.

Recommendations

Place the keyboard on a stable, flat surface at a comfortable height for playing. Use a dedicated USB power adapter rated for at least 5 W when a computer USB port cannot supply sufficient power. For quieter practice, use headphones; for teaching or small group demonstrations, use the built‑in speakers or connect to external amplification. Regularly check cable connections and avoid exposing the instrument to moisture or extreme temperatures.
