Appendix IV. Troubleshooting
| Trouble | Possible Reason / Solution |
| A slight noise is heard when turning the power on or off. | This is normal and nothing to worry about. |
| After turning the power on to the keyboard there was no sound when the keys were pressed. | Check the master volume is set to the correct volume. Check those headphones or any other equipment are not plugged into the keyboard as these will cause the built-in speaker system to cut off automatically. |
| Sound is distorted or interrupted and the keyboard is not working properly. | Use of incorrect power adapter. Use the power adapter supplied or the batteries may need replacing. |
| There is a slight difference in the timbre of some notes. | This is normal and is caused by the many different voice sampling ranges of the keyboard. |
| When using the sustain function some tones have long sustain and some short sustain. | This is normal. The best length of sustain for different tones has been pre-set. |
| The master volume or accompaniment volume is not right. | Check that the master volume and accompaniment volume are set correctly. |
| In SYNC status the auto accompaniment does not work. | Check to make sure Single Finger or Fingered mode has been selected and then play a note from the first 19 keys on the left-hand side of the keyboard. |
| The pitch of the note is not correct. | Check that the transpose is set to 00. |
| The keyboard appears to switch itself off. | This is the power-saving feature in operation. See page 6. |
