Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Keyboard does not power on. | Low battery or power adapter not connected properly. | Charge the battery or ensure the power adapter is securely connected. |
| No sound from speakers. | Volume too low, headphones connected, or speaker malfunction. | Increase volume, disconnect headphones, or contact support if problem persists. |
| Keys feel too stiff or unresponsive. | This model features semi-weighted keys, which naturally have more resistance than unweighted keys. | This is normal for semi-weighted keys. Continued practice will adapt finger strength. |
| Sustain pedal not working. | Pedal not connected correctly or incompatible pedal. | Ensure the pedal is fully inserted into the correct port. Verify pedal compatibility. |
| MIDI connection issues. | Incorrect cable, driver issues, or software settings. | Use the correct USB-C cable. Check computer drivers and MIDI software settings. |
