8. Troubleshooting
If you encounter any issues with your Moukey MEP-120, please refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound from speakers/headphones | Volume too low; headphones connected; power issue; faulty connection. | Increase volume. Disconnect headphones if using speakers. Check power adapter connection. Ensure cables are securely plugged in. |
| Keys not responding or inconsistent volume | Dust or debris under keys; internal sensor issue. | Gently clean around the keys. If problem persists, contact customer support. |
| Bluetooth audio lag | Bluetooth is not designed for low-latency audio output on this device. | Use wired headphones connected to the PHONE jack for real-time audio monitoring. Bluetooth is primarily for MIDI data. |
| Keyboard stuck in demo mode / cannot adjust volume | Software glitch; incorrect operation. | Turn the keyboard off and then on again. Refer to the detailed operating instructions for exiting demo mode and adjusting volume. |
| Sustain pedal not working | Pedal not connected properly; faulty pedal. | Ensure the sustain pedal is fully inserted into the PEDAL jack. Test with another compatible pedal if available. |
