Troubleshooting
| Trouble | Possible Reason/Solution |
|---|---|
| The digital piano will puff when it is switched on. | Don't worry. This is normal. |
| Pressing a key makes no sound after the power is on. | Confirm master volume is set properly or if the headphone jack is linked to other devices, which automatically cuts off the built-in speaker system. |
| Notes have slightly different quality under the same sound. | This is normal due to different sound sampling ranges making different sound qualities. |
| In pedal sustain function, some sound sustains longer, others shorter. | This is normal. The sustain of different sounds has been set to optimized length. |
| The sound volume is too small. | Confirm master volume button is set properly. |
| Some MIDI Data can not be transmitted correctly (Even the MIDI cable is linked correctly). | This is normal. It is related to the original setting. |
| There are two sounds at the same time while playing. | Dual voice function might be on. Turning it off can solve the problem. |
| The tone's pitch is wrong. | Turn off Transpose function and restore Master Tuning to default. |
| No automatic accompaniment chord. | Automatic accompaniment chords function is currently not available for this digital piano. |
| Key touch is different from before. | The digital piano has 5 touch sensitivity levels. Adjust touch sensitivity again or reset to default. |
| The speaker will make noise when a cell phone is nearby. | The cell phone may cause interference. Turn off the cell phone or keep it away from the digital piano. |
| The pitch doesn't match with the key while playing. | Twin Piano or Transpose function might be on. Turn off Twin Piano or reset Transpose to zero. |
| The sound can not be changed while playing. | Twin Piano function might be on with the split point set to the highest pitch. Turn off Twin Piano and reset the split point. |
| The demo song distorts or interrupts. | The circuit board's self-protection system might be activated due to overheating from prolonged use at maximum power. Turn down the volume or turn off the power for a while. |
